This is a GREAT throwing putter. I have had an ultrium and a basic in my bag for several years now and it has been an absolute staple... for throwing. I tried putting with them for a while and while not horrible, there are much much better options for putting. This disc is very fast and very stable. I can rip this full power and get it further than any other putters, and it wont flip or turn. It doesn't really fade very hard, kinda just drops, which is useful. Thrown with enough anny it'll hold that line well, and thrown with hyzer it holds the line great. If you're looking for a really workable throwing putter that can handle some power try this out. Great disc

Plastic feels amazing like a really gummy star or esp flex. Medium rim depth, deeper than my Zone & Ringer, but not as deep as my Harp. Rim also has a fairly large bead. 
Flight: Back hand flies very straight with stable finish on 70-90% power throws. Forehand on power throws had to give it some hyzer so it would flip up and glide straight. On touch forehands i could release it flat for a straight flight with a stable finish.
I would say its a bit less stable than a zone/harp, but very similar to a Ringer. Its not taking my zones slot or my ringers yet but when my jawbreaker ringer eventually gets too flippy I'll have a replacement and once this Ultrium plastic feels amazing going to have to check out their other discs.

The Jokeri is a fantastic approach disc with it's dependable fade while not being super beefy.

I've got this disc in every plastic they make it in and they fly pretty consistently across plastic types, obviously the basic plastic beats in faster but overall a very good alternative to discs like the Zone

Fantastic one round disc. My go to approach, especially on windy days. Has a good amount of glide for being so turn resistant. Great off the tee.  Bit less stable and deeper zone is a good comparison.

Basic is a great putting plastic. Will wear with use. Keep out of the heat. Will grip the ground and stick. Ultrium and premium are excellent for approach, not terrible putting.

Can't wait for the Platinum flex

The ultrium is absolutely the best plastic I have ever felt. Tough, grippy, and and absolutely beautiful teal color. This is my go to disc for overstable approach shots within 200 ft and it does literally the same thing every time no matter the conditions. Even with anhyzer this disc will come back fairly strongly left if given enough time in the air.

I will say that this is NOT a putting putter and while it grips the chains very well I find the design neigh impossible to spin putt accurately. As an approach disc this will not be leaving my bag any time soon though.

This has been my main stable/overstable driving and approach putter since it was released. No other disc has been able to replace it as of yet. It can also act as a short mid-range disc. It has a lot of distance for a putter. You can also use it for putting on windy days since it's so stable. I can crank it and it won't even think of turning, it just goes straight for a long ways before a reliable fade kicks in. This plastic is so nice that even with heavy use for many many years, it still looks and flys like new. Some of the toughest and nicest feeling plastics on the market. I have one of the first runs, and it has more of a 3 fade than what is listed here. Maybe the mold has changed some, since these first runs. 

One of my all time favorite discs. 

I didn't have the Joker 24 hours yet and nailed an ace with it. Need any more? I am a senior grandmaster with a noodle arm and this is the first overstable disc that I have been able to throw. I've had it a week and have not made a bad shot with it. It flies like a dream come true. Extremely accurate and reliable. And Prodiscus plastics and hands down the best plastics on the market. Nothing else comes close. Talk about grippy! And Ultrium is plastic taken to Jedi level!

I throw the Jokeri in all three plastics.  All of mine are 175-176 and work for different types of shots.  The Basic plastic isn't the most durable so it beats in to nice and straight after only a few rounds.  I actually putt with it 50% of the time.  I push putt and I like this when there is a bit of wind vs my Reko.  The Ultrium plastic Jokeri makes for a great thrower off the tee.  After 2 seasons my oldest Jokeri finally stated losing a little stability but it still has a consistent if more gentle fade.  Lastly is my Premium Joekir which throws like a longer Prodigy A-1 or Zone.  Pure beef.  Always finishes left. Zero turn.  I find the Premium plastics across each Prodiscus model to be more stable much like Champion vs Star.  The only exception to this is their Slaidi (see my Slaidi review for details)

I believe if more people got their hands on the Jokeri they would be all over course.  Great for flicks, super comfy in the hand.  Seems too like Prodiscus USA or Prodiscus in Finland has finally gotten their act together about distribution because for the longest time you could not find these discs.  That has recently changed and they are available! Grab an Ultrium and Basic today if you can find them.  

The perfect overstable putt and approach. The Jokeri can handle a great amount of power off the tee. The Jokeri can handle touch forehand throws with ease. The Jokeri can handle wind very nicely. The Jokeri is so much more comfortable then it's overstability would suggest. The Ultrium plastic is beyond any plastic I've felt, smooth but with so much grip and just enough flex.. Amazing disc.

One of the best disc I've thrown period. The ultrium plastic is amazing it's so grippy but also very firm and very durable. I would compare this disc to a harp but better imo. It's over stable and can smash on a power throw while at the same time be great for a short up shot that sticks by the basket. It feels great in the hand (more comfortable than a harp). I will be buying several of these 

I picked up my red 175 jokeri a couple weeks ago right here on infinite disc. As always the disc arrived quickly and exactly as advertised.  My jokerI is molded in ultrium plastic. It has a very shiny look to it.  when I first got the disc, I threw some practice throws out in the yard. I thought the plastic looked as if it would be slick when wet so I soaked it and my hands with the water hose.  To my surprise the ultrium plastic provided the same great grip when it was wet as when it was dry.  When throwing from the tee, the joker takes a straight flight path with solid end of flight fade. It lays down pretty quick once the fade kicks in. I found it to be easily rangeable and predictable. It's pretty decent as a putter to if you prefer  an overstable disc for long range puts. The only thing that I have any complaint about is that tree hits will scuff the ultrium plastic. Not really damage,  it just leaves a dull look in that shiny surface. Overall great disc for the short game.
