Review on Reliable OTC Wrist Thumb Splint Support Neoprene: Enhanced Comfort & Stability by David Herrera

They work but I've had a different pair since 1996 from my therapist. They were starting to wear out so I took one of them to try as a replacement. It started falling apart at the top seam of my thumb after only a few weeks (and I don't wear them every day - only when my thumbs hurt). The building doesn't impress me.
