Had this thing for about 2 years now since 2 decembers ago. I won it from a raffle when it first came out. This thing is great! I wanted tracer units but never wanted to invest in it. Then i won it so my day was lucky!
This thing is crazy awesome in CQB arena's or night games. I actually like it in CQB better because you can guarantee your hits and get people in trouble when they dont call them since you can see the BB near perfectly hit them.
I dont know about the previous review....This barrel extension has been through HELL and back!!! I've slammed this thing around so hard in some of the nastiest battles in the middle of the jungle and even used it during a rain storm (it doesnt even have O-Rings on it but the threads are so fine it doesnt matter, i'll probably teflon tape them for future safety. Anyways to this date it is STILL working! Tube is not shattered and batteries still charge and i've even taken this thing apart once to realign the tube since i slammed it out of proportion where my BB's were not shooting straight. Such a simple unit to take apart i like it so much! Internal build quality is very good.
-Batteries charge QUICK Cant judge run time, it's never been used too long.
-Extremely durable....it's been through total hell on earth
-Not too long or bulky
-Very nice looking
-Screws on very nicely, good threads fits on most of my guns easily.
-Charging is delicate, make sure the cord stays in and doesnt get bumped or it can pop out
-Damn power switch keeps getting hit on by accident and wastes battery power. Cutting it short and recessed can fix that problem.
Overall it gets a 4.5 out of 5 due to annoying power switch though problem is fixable easily.
