I had issues with my wrist in the past, I didn't blame the strings or the racquet.... I coach told me I was pulling out too soon on my 1HBH...I followed his advice, but first I took off one month from tennis. No wrist issues ever again.
Have a good coach checking your technique. It could be part of the problem too.
