If you are not only playing a guitar sitting, you need to buy this thing. Even if you sit like me 99% of the time, you should buy this.
Usually I am practising while sitting and my strap is over me. But sometimes I get up (with guitar) to adjust my amp ar grab a phone. And in that crycial moments your guitar is in danger. When you sit strap becomes loose and may easely lose the right position, so when you get up it's so easy for strap to unhook. I know whats i'm saying(
But this things won't let you guitar to crush. I tried to pull the strap as hard as I can, but it stayed in place!
Overall: super tight, great quality, only the surface is not as smooth as in the photo.
