My local course has 2 holes where over stability is a must off the tee for a righty. 1st one is 284’ uphill disc went about 250’. The other hole is 245’ flat around some trees. Disc landed 6’ from basket, so an easy 5star from me. Disc did everything I wanted it to. Its not going to glide super far, and its always going to finish stable.

It lives up to the hype! I was told the BUZZZ is a must for beginners so I picked one up in the Big Z and wow it's so easy to throw. 

My other beginner friends would throw their drivers and while I throw the BUZZ and I'm out driving them by 20-50 feet. The BUZZZ is very user friendly and forgiving, I will be picking up 2-3 more so I can practice without having to run back and forth.

This is my second review for the Buzzz OS. 
The first review was for the ESP and this one is for the BigZ.

I found a Big Z Buzzz OS with no name and no number thought it would be exactly like my ESP but they could not be more different discs. The Big Z is less stable, more workable, glides farther, yet still comes back every single time. This went in my bag right away and kicked out my ledgestone wasp and Malta. I can't think of a better complement for my Buzzz. I love this disc so much, I even slid the ESP back in to use stictly as utility. 

This flies exactly like my ledgestone wasp (more OS than a normal wasp) and Malta but this disc always fades back at the end of the flight where the other two have a tendency to flip over completely if not thrown high. The Buzzz OS is simply more consistent and can be trusted time and time again.

Now i see what all of the Buzzz is about.... Get the Buzzz OS and get it in Big Z.

Feels just like the Buzzz. It is overstable for sure and is very reliable into headwinds which is when I break it out. It will not come out of an anhyzer though into a headwind, it needs flat release to make it work. This can be used for touchy forehand upshots too. Very nice complement to the Buzzz.

If you love the Buzzz and are in need of a very OS midrange, then go no further than the Buzzz OS!  This disc has the simliar wing of the ever-popular Buzzz, but with a nice Flat Top.  IMO out of all the midranges I've tried the Buzzz OS feels the best in the hand when throwing forehand (which is probably 90% of my game).  When I need a little more distance than my zones can give, I switch up to the Buzzz OS.  It flies similiar to the zone, but with that extra glide that just lets it go further before that nice dependable (and somewhat beefy depending on your power) fade.  I currently bag the Big Z Buzzz OS which looks sick with the nice Buzzzy Bee on it!  If you like to flick putters and mids, then you need a Buzzz OS!

As expected the feel of this disc is very similar to a Buzzz, but slightly shallower due to it's flat top. This was my first overstable disc and the first disc I used for forehand throws. That being said, I mainly use it for utility forehand hyzers and short tomahawks over obstacles as it has sharp, reliable fade. The Z plastic is nice and grippy, and the slight pearlescence makes it shiny and easy to find.

When people talk about super overstable mid ranges, two of the discs that always come up are the Gator and the Buzzz OS, however, these discs are nothing alike when it comes to the feel.

Where the gator has a deeper profile and a bead, the Buzzz OS is super flat, and has a very, very low profile. The profile might even become a bit of a problem if you've got big hands. I recommend grabbing this disc in person before/instead of ordering it online. For me it's mostly a sidearm disc.

I cannot really say much about the flight of the disc, other than it glides a fair bit considering the low profile, but it sure dumps in the end. A very, very reliable disc for those short midrange upshots. I also like this disc for 80-100m flex shots when you need to dodge the brown and green pillars on the course.

Feels just like a Buzzz in the hand, but flies with a consistent over stability.  Great in any wind, I never have to worry about turning this one over in a headwind.  I throw a buzzz all the time and the fact that this one feels the same makes one less thing I need to worry about before each throw.
