Poor quality. Not very effective.

I rarely knit in the summer. I garden. This summer, my thumbs began hurting at the joints for the first time. It worried me since I use my hands for a lot that I do. When I saw the ad for these braces, I thought I'd better get them onboard, since my thumbs are very involved in knitting also. In short, I haven't had a chance to try them out yet.

Great
