Just got my Cheetah today and put it together on my lunch break. It hits super hard and was really simple to put together. The instructions aren't the best but they weren't really necessary. The Scar barrel is a nice accessory and really helps with the accuracy, although I might need to put some tape between it and the barrel to keep it stuck on better because it currently falls off more easily than I would like. Can't wait to see what kind of FPS I can get out of it!
I would definitely recommend this to other foam dart enthusiasts, it's affordable, simple, easy to put together, and right out of the box can compete with a lot of other more complex and expensive blasters.
Hands-down one of the best price-for-performance blasters out there. Some simple assembly required. Love the SCAR barrel it comes with!
