I had a pretty bad wrist bend, so I bought this glove and gave it an honest try for a number of days. The straps weren't strong enough to restrain my wrist, so I really didn't notice an improvement. Maybe I didn't use it long enough... but I really felt like it wasn't doing much and found it a little uncomfortable to play with.
A few months later after a lesson with Max Eberlee he got me to change my stance a bit, to open up my stroke. Once I got my stroke out of the way of my body (and with some hard work) my wrist problems started to disappear.
So to summarize, the glove didn't really work for me, and even if it had worked I would've been ignoring the underlying problem with my stance.
