I don't know why it didn't "work" for the other reviewers, but for me it was a perfect application. I have large hands and it is the only one that fit easily, it was secure and did its job perfectly, without putting pressure in the wrong places, like for example at the fastening point.

It's not worth it at all.
Apart from the fact that it doesn't support the contact point well, the adhesive Velcro easily comes off, making it non-functional.
It's better to get some other product
