Very disappointing. The racquet broke on the first day with normal use. I cut two rails and on the second one I noticed a lot of vibration when copying the end. And now one of the grooves came out clean. Didn't you know I went through the return window for a day. On the plus side, I'm really glad I noticed it with a vibration and not a splinter stuck in my stomach! Needless to say I will not be buying again.
