Bought this for my bass guitar. While I don't experience the BB234 to be particularly heavy, the extra strap width and padding provide a lot more comfort. Lately I tend to play more in the standing position, so getting a better strap is good upgrade.
I find strap to be sturdy built, well padded and well sewn. Ends are firm and thick. I don't see them easily coming of the strap buttons, at least not in home or studio use. It is long enough for comfortable (matter of preference) playing position (I am 189). I use it as it came, no length adaptation. I could get about 20-22 cm more length if needed.
76+ cm straps are better choice over standard 50 cm in many cases, but especially if you have a heavier instrument. If you are looking for a such strap, this one is great option.
