This product is cheaply made and isn't up to the quality I expected for the money I paid for it. I took the chance because there were no reviews on it.

If you are trying to fix a wrist breakdown in your golf swing I would get one of those golf gloves that does not allow your wrist to bend. I have one and I like it much better. 1 star

This product is very cheaply made, and did not work very well for me. My main problem with this product is that it doesn't address the core of the problem why your wrist doesn't stay flat at the top.

A flat left wrist at the top all begins with having a good grip. If you aren't gripping the club correctly, you are going to have to force yourself into a very awkward feeling position in order to keep your left wrist flat at the top. This will probably only mess you up more in the long term. 1 star

Different strokes for different people maybe . I found this little item brilliant and while it seems a little "lightweight" you wouldnt want anything bigger or heavier on your wrist . It works for me and only took minutes to sort out my "worst" swing flaw. great , I love it . 5 stars
