Not sure yet
I have used for about a week. I have looked at instructions and videos but have difficulties getting splint on. I am editing this review on 1/11/2020. I have now figured out how to properly put on splint. Or at least I believe so. My pain level has decreased especially first thing out of bed. Hopefully I will get more adept in getting it on. Sleeping with it is fine.
