One of the best understable putters in the game.  On flat release, it will pan right (RHBH) for the entire flight with only a small check-up if thrown too nose up.  I have used all of the plastics and they all are great.  Atomic is pretty close to the Star and starts out the most stable; their champ plastics are slightly less stable, followed by the rubber blend and, lastly, the DX.  This disc can replace a FH. On hyzer it will flip to flat and then start to roll over into an anny before flattening out.  

This is a great option for an understable throwing putter in cosmic or atomic, possibly the furthest flying putter I've used! A great first disc for newer players as it's glidey and stays straight under low power.

This disc is the king of touch.  It basically goes where you throw it.  Give it just a nice flick of the wrist and it will go dead staright.  Put it on hyzer and it may flip up and turn a little but will finish fading.  Throw a gentle turnover and it will float all the way turning without diving off.  This disc helped me to understand the importance of touch in disc golf.

My go-to throwing putter - holds any line you put it on.  Shallow - doesn't feel "putter-ish" in the hand.

I've found it especially useful it the most for when I'm scrambling and need to hit a certain angle - any release angle will hold the entire length of the flight

First this disc completely fixed my outside the circle putting. And then overtime it replaced my actual putting putters. The strata and magma are SO GOOD to putt with. Dead straight. The atomic, cosmic and glow are amazing throwing putters. Easy to throw. Extra glide. And will hold a turnover all the way if you need it. "Tui for the 2! Tui for the win! Throw the Tui for the 2-ey!" Freaking love this disc. Feels great in the hand. It's the definition of "stable." Not OVER stable. Not UNDER stable. It's just super straight and I love the RPM plastic choices.

Great disc for Beginners, Amateurs, and Professionals alike. Stable flight with a ton of glide. Slim profile with a bead. Less stable when flat. More stable when domey. Comfortable rim with a flight comparable to a Comet. 

I have this disc in Atomic plastic at 173 grams. This is an understable putter that is also very shallow. It has a comfortable feel for me. The plastic is superb. Durable and grippy. Medium to firm flex.

This isn't a disc at my power that I rely on too much. I throw it mostly for shorter 200-270 foot turnover shots I don't want to fade. Once you start pushing the power beyond 270 is gets hard to control. But it is also fun at the same time. Putting it on basically a spike hyzer line and watching it flip up and continue to straighten is a thing of beauty. Just a fun disc to throw and stable enough for shorter approaches.

I adjusted the ratings slightly. 3/5/-2/0    

This disc right here is the most unique mold I have ever thrown! This disc is very touchy. I feel like for a beginner it is a must have! But for an advanced player I would still say it's great! I gave it 4 stars because it is pretty touchy but when you get this thing on the right line with the right power it stands up and glides literally until it can't spin anymore and just falls to the ground! Also Great for Annys you don't want to come back. It's a very shallow mold with a small bead that feels very comfortable in the hand all in all another great mold from RPM! Also the most glide I have ever seen on a putter

This is a unique disc. I've never seen a disc that has nearly the same flight path at full power and half power. It's smaller in diameter, so it might feel strange at first, but just try it. As a driving putter or approach disc, in Atomic plastic it has a slight (-0.5) turn and just a subtle of a fade (0.5). The fade isn't really a fading turn but more like it just falls out of the sky at a very low speed. Can take a lot of power too, which makes me wonder how many mids do I really need in my bag. I can't throw this as far as a Warship or Fuse or Piwa, but close. If you are looking for a longer Mako with the same flight characteristics of the original Mako, this may be it. Looking for a straighter Pure or a Warden without much fade, this may be it. Looking for an Aero that is more versatile, this may be it. I still need to try a bunch more putts with it before I can comment on short range stuff.

I use the tui as my approach disc. It very accurate and can be thrown backhand and get a reliable turn to the right which great as a primarily backhand player.

I have two Tuis, both in Atomic plastic, 171g and 174g. The lighter one is a miracle disc. The heavier one is good too, but I've not thrown it enough, yet, to grant it sainthood. 

Numbers-wise, my lighter Tui is a bit faster (4) and glide-ier (5) than they say, but -1 turn and 0 fade seem about right. 

Atomic is a great feeling, tough, grippy plastic, grippier than old Goldline. It's not quite as grippy as Kastaplast K1, or, my new favorite: Legacy Icon. It feels like the flexy/grippy Armor plastic on a new Viking Cosmos that I have. 

I've been throwing my lighter Tui for about half a year. A few times, I've thrown it almost 350ft (which is about my max, with any disc)--in an almost perfectly straight line. It has ka-chinged into the basket from 100+ft away numerous times. It LOVES playing in the woods--it doesn't rise up if thrown hard (unlike, say, a Patriot, or STARi). If thrown with a slight hyzer, it flips up and flies straight--for a long long way. If thrown anhyzer, it holds it and curves right (but not hard right, like a STARi). If given lots of hyzer, it stays hyzer and goes left. 

For years, I threw a Latitude64 Goldline Fuse, and thought it was the perfect ONE DISC  (which is how like to play) (well, I still think Goldline Fuses are the perfect ONE DISC), but the Atomic Tui has joined that rare club. It's slightly slower than a Fuse, but easier to putt with. Five stars--a perfect mid/approach/one disc--for sure. 

This putter is just excellent.  I quickly found out this is NOT a driving putter (I figured that from the flight numbers, but had to give it a good rip out of curiosity).  But, if I'm careful with throwing power and release angle I can get this out to 250-300' without much trouble.  That said, I won't use this disc for any approach longer than 200'.  Anything shorter than that, I can easily control its understability.  It is absolutely perfect for anhyzer approach shots because I can release it gently with good control and touch and trust it to hold its anhyzer line towards the basket.  Many putters will begin to fade at the end of their flight when thrown gently, where this resists that effect making it incredibly useful for certain shots.  I find it has more turn than advertised, and more glide, so I adjusted my flight numbers a bit.

Scrictly putting, the disc also resists low speed fade better than most putters.  This makes for dead straight putts even from circle 2.  I like this, but I have to account for its flight path being straighter than other putters I still throw.  Not being used to this at first, thinking it would fade left into the basket like my other putters, I'd putt and this would just continue dead straight past the basket missing on the right.  But, keeping this in mind, this is my favorite putter for long putts.  Personally, I sometimes find it hard to calculate fade properly on a 40-50' putt, so with this I just put it straight at the basket from that distance and it works beautifully.

I'm sure there are other understable putters out there that fly similar to this one, but none that look as good!

This is my absolute favorite approach disc when I need to go laser beam straight.

I have this disc in all the plastic types. The magma tends to be the more understable.

Atomic, for me, is grippy and durable. Love the flight. Love the confidence I have with this disc.

It took me a week of throwing to realize just how true the flight is. At first I was trying to help the disc by modifying my release angle. Turns out... flat release equals straight flight.

Always a fan of the factory stamps too. Good job RPM.

Check out our review on this awesome putter! 

The Tui is a special disc! Don't let the fact that this is a putter fool you. For an advanced type player, you can throw this on a hyzer flip line and it will go for days! It will also hole an anny line like a champ! If I had to compare this disc to any other disc, it would be a beat in gold line fuse. I love my fuse, but I also bag this tui for a slightly less stable version. Great disc!

Wow, do I love this disc.  Starting with the presentation, this by far the prettiest plastic in my bag, and it feels exceptional.  The closest thing I could compare it to is the smooth, pearly finish of a surfboard.  Onto the flight path-  Arrow straight, slightly understable depending on how much power you give it as the numbers suggest.   It's a putter/midrange mix disc that I would recommend to anyone looking to try a non-mainstream brand...who also appreciates beautiful quality.

This disc is awesome.  The atomic plastic feels great and has a good grip with a clean release.  I'm talking about driving with it.  Put it on a slight hyzer release and it will flip up and glide lazer straight forever.  Holds a great anny line as well.  The stratus plastic is also great for a glidy putting putter.  I use it for long, open putts.

The Tui by RPM is a great all around putt/approach disc. Very controllable for its understability. Great for throwing off the tee or straight putts.
 

as far as throwing from the tee? If you nose it up and crank it?

This putter glides far and controlled with an anny release.

And RPM plastic is SUPERB. Seriously. My other discs in discraft, Innova, and Trilogy, all in premium plastic, feel cheap after throwing an RPM disc in Atomic plastic. 
(RPM Atomic plastic and Kastaplast K2 are in my opinion the best quality out here right now).

the magma hard plastic from RPM is like Atomic plastic but more "chalky" and grippier.

So i give the Tui in Magma hard plastic 5 stars. And i give the Tui in Cosmic plastic or in Atomic plastic 5 stars as well. 

I was impressed with the Tui in the Atomic Plastic. I was testing a wide range of discs, and I was throwing the Tui consistently farther than some of the midranges I was throwing. It was somewhat windy, but nothing too terrible. I was testing the Tui alongside one of RPM's midranges, the Piwakawaka. The Tui was out throwing the Piwakawaka almost every time. I think the reason was because the Piwakawaka is an understable midrange, while the Tui is more neutral. 

I loved how straight the Tui flew. It had amazing glide and held up in all wind conditions except a headwind, which was expected. When I really cranked on the Tui, it required a little bit of hyzer release because it is slightly understable. But when powered down, the Tui was dead straight. I loved that it flew so straight and that I could get it to go farther than the midrange discs I was testing out.

I have yet to try out the Tui for putting, but I know this disc is an awsesome approach disc. It is reliable and very straight. The glide will impress anyone, and there was just barely enough stability for it to hold up in wind conditions. The headwind was flipping over the Tui every time, but not bad enough that it would cut-roll. It was still predictably understable in the headwind, and might still be good for when you need a big turnover shot in a headwind.

If you are looking to try something new, I would definitely suggest trying out the Tui. The plastic feels amazing, and the mold is nice to feel in the hands. The flight is predictable and overall I like this disc a lot!

My first impression of the Tui was that I had to change putter immediately...and that was without throwing it even once!  That is how beautiful the atomic plastic from RPM Discs is! I wanted to select my favorites and start a collection. The plastic doesn't only look beautiful, but it feels great with the perfect mix of durability and grip. RPM's base plastic is perhaps more along the lines of other popular putters, but this premium Atomic plastic is worth every penny. 

The profile of the Tui is very shallow. It doesn't have a very deep pocket and the rim is not very deep. I traditionally like these low-profile putters, so it felt very good in my hand. It is probably a better "driving putter" than a precision putter. It flies really well when given a little heat, something like a Dart or a Colt. It is a great putter with mid-range potential. 

RPM Atomic plastic is some of the best feeling plastic on the market. This plastic blend is grippy, slightly flexible, and looks really good too. I'd compare it to a more grippy, more flexible Latitude 64 Gold Line.

The RPM Tui is a super straight disc to throw. While it's listed as a putter, the shape and feel of this disc is something I'd never putt with, except for maybe long putts which worked very well as this disc glides very well. If I'd compare it to any other disc I'd say it's kind of like a beaded Innova Dart.

In terms of driving, this disc is great if you want a perfectly straight shot down an aisle of trees. It's not a Frisbee, and still will fade slightly at the end of the flight as it slows down, but not much. The TUI is ann outstanding disc for anhyzer throws. It holds an anhyzer line line very well.

The TUI is a fun disc to throw and can be used by players of all skill levels. If you love trying new plastic, I recommend trying RPM from New Zealand.
