-Grips the tank nicely
-Comes with a free barrel condom
-Zipper on mine is a little hard to close
I have a Java 45/4500 N2 Tank with an NXe Tank Cover. This fits my tank very well. It hugs the tank and has little to no movement. There are small grips inside of it that keep the tank from slipping around, much like DYE's Rhino Cover. On the back are two no-slip grips to keep the tank from slipping around on the players shoulder. The only problem I have with mine is the zipper. The zipper on my tank takes a little force to close, but it will close. NXe products are widely used by professionals, and now I see why.
For $20 and a free barrel condom, I'd definately say get it.
