I've been using these picks for over a year now , for an at-home practice pick I find it a great fit not too big or too tiny and as long as you are practicing, the life span of these picks is as good as any high quality pick.
This is my personal opnion taking into consideration I play in a metaI band and have a strong right hand attack, the picks only last about 4-5 concerts, and then the edge is rounded, I also have a problem with the lack of grip when I play concerts, seems to slide around a bit, but because of its size its never a big deal, just personal opnion
All in all a great pick!
