This is the first splint that I have found to actually truly give me support and relief from my severe pain from having both severe CMC joint arthritis and severe De Quervain's Syndrome in my left hand. This splint is also universal so it can be worn on either hand which is so much easier than having to buy multiple splits. The thumb compression sleeve is nice and relatively comfortable, although it gets a bit snug on my thumb, especially when it's swollen. The compression sleeve does help reduce the swelling. This is the best Splint I've found so far and the price is fantastic comparatively speaking. I have a thumb spica splint as well, but it's big and bulky, although it does support the thumb well, it just gets in the way. This Splint can be worn while I'm working as a nurse and I can actually wash my hands and not have to remove it. It's perfect for what I'm needing.
