The air cells are very comfortable and am happy overall. Should have gotten a shorter one in retrospect, I keep this one as short as possible.
The leather bits at the end are very rigid and after taking the strap on and off literally 3 times and using it for 2 weeks I see wear and I wouldn't feel safe using this on my Les Paul after a year or so. The leather part is very thick and is very hard to put on. Compared to my cheaper Levy and Fender straps, much lower quality.
