To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Other reviews aside. I personally like the bands. I am older and suffer from arthritis in both hands. For me, this is a great tool. Keeps my pinky and ring finger from wandering off. When they first arrived I was only able to wear them whole playing for about five minutes. Still on a single band but not quite a full month late and I can wear them a full hour. My personal goal is to get up to two hours and I will use them while playing gigs. I personally feel that my hand shape and finger strength have improved. I have thrown away countless amounts of money over the past 46 years playing on so called tools and aides. Funny how the least expensive and simplest one in my tool box is the one that works.
