I wanted something which looked a little bit better than the tried-and-trusted hairtie method to stop ringing sounds on my guitars and bass. The fretwraps are perfect, though I do have some concerns.
The quality of the padding isn't fantastic, I can feel already that it may break down over time and I don't imagine I'll be able to use these after a few years if I keep adjusting them. The sizing guide on the gruvgear website could do with being updated as these definitely won't fit SOME five-string basses (I play Ibanez BTB's with wide spacing)
Already, some of the threads have come away from all three in the pack.
Finally, the velcro is very poor and doesn't provide enough hold to keep the fretwrap in place, especially if using it as a mute over the fingerboard (instead of behind the nut)
With all that said, they are very cheap and extremely useful. I would buy them again, but I would pay attention to the sizing differences a bit more.
