I bought these at the same time as the 5" Yost Vise. I like my visa very much. These cheek covers are so-so. You are super fat. Soft and rubbery. The magnets are not strong and will break with minimal use. I think their material could be thinner and the material could be harder. I don't have anything else to use so I'll use this and get by. Today I used a terry towel to hold some of the fittings which I didn't want to damage, I had to because these cheek covers are too soft to hold the fittings when tightened. Fittings simply rotate while being clamped into these jaw covers. I cannot recommend them.
