Got to use mine recently at a walk-on and I was very impressed. I'm running it on a remote so the weight and balance is fantastic, had no issue with the remote preventing me from switching hands. The loader system was flawless, even when getting low on paint it wasn't too much hassle, by tilting forward you can pretty much get down to the last 2-3 balls before running dry. Even out of the box it had a very consistent velocity and I really like the 'thud' shooting feel of the Axe internals, I've left everything at the stock 200psi, although I might tune/tweak it eventually I'm in no hurry.
One thing that's taking some getting use to is first shot accuracy. It's no less accurate than any other gun but due to the fact that you shoulder it a bit differently to a regular marker/bottle setup I was having trouble getting those first shots to hit the mark. I'm sure I'll improve with practice over time.
Finally, the one 'issue' that I found, the selector switch. I found it too large and easy to knock into different modes, this went from the annoying (safe) to the dangerous ( full auto). Ideally I'd like to configure the selector switch to toggle between safe, semi and ramping but this isn't possible as when it's enabled you're locked to the 3 default fire modes (semi, 3 shot, FA). The only alternative is to lock the gun into a single fire mode which is what I'm probably going to do next time I play. One thing that would be nice would be a smaller, lower profile selector switch to minimise accidental changes, like you can get for firearms
If I can pick up a spare selector arm part (num 72774) I might make one myself
