I was looking for a cheap, light and good quality rack bag for my AxeFX2 and that was a perfect match for my needs.
Before you panic, you will find 8 screws and washers in the big pocket.
Installation was a breeze, perfect fit, enough space at the front and back (so the Axe won't get damaged under normal circumstances).
Being a 2U doesn't leave much room (if at all) at the top, bottom and sides but that's the point of a perfect fit. I don't expect any overheating issues (but if I deal with any during the summer, I'll just update the review).
The zippers are kind of stiff at the ends (when you totally unzip the front and the back side) but chances are they are of good quality. They certainly look big and sturdy so time will tell.
The protection for my use seems adequate but I don't need extreme protection anyway.
The big pocket is a great addition as you can throw several cables in there.
Good purchase!
