Yes I do enjoy your products (two racquets and one pair of shoes) and I think they are a great value and also I think your service is great (preparing racquets and shipping). I will buy from you in the future again. However there is one minor blemish on your record. The Prospeed strings on the Lethal 6 racquet broke just after two games (and I don't hit very hard :-) ) so I had to re-string it which here in Canada is not inexpensive but I won't hold this against you. :-)"

The only one complain I got so far was a string that broke on purchase and a new replacement didnt last much either. This is a minor situation possibly due to the user himself.

Excellent Shipping, packing and delivery. I have no complaints ther ...»
