The thing is great, helped cut the velocity spikes by half. Also nice to be able to know what pressure the LPR is set for and be able to change it according to climte and altitude (I play at 1 mile high, Denver). Sonic now makes an air adaptor that act as a valve chamber. Like the ones you see one Spyders and Cockers. It allows you to use what ever inline reg you want. Im using Sonic's Gladiator inline reg. Very high flow, with a reg seat that will not crap out on you like air America's do. The combination of Sonic parts on my Defiant has put my velocity to +\- 2fps. I set my gun at 298 at tournaments and never get a hot gun. Oh Yeah, and check out their air systems Mac Attack or the new Conquest (the one i'm using) super high flow.
Weaknesses:
Not a damn thing wrong with any thing Mac Development makes. I even have a Sonic Cocker, sweetest cocker i've owned (out of like 15).
