I bought two of these clamps to replace the composite ones that were cracked. The clamp worked great just like it was advertised on the website and YouTube, the grip was already perfectly adjusted, didn't need to change for the string that I use (16 or 17), it is strong enough to hold the string in place, but won't creat the mark on it, so far I have strung 10+ racquets, didn't have any problem.
Lifetime replacement warranty is any other great feature for this product, though I don't think it will break if I use it properly, but it gives a peace of mind.
Replacement Double String Clamp
Excellent clamp, Holds the string in place. I'm definitely going to buy another one. I just don't know from whom. Your service was great, everything was good. I'm just not used to such a long delivery time. Not your fault, but USPS.
Great product at a great price from a company with top-notch customer service. It is easy to be a loyal customer of Klipper!
Great Customer Service.
I had some string jobs I needed to do within 10 days, but one of the clamps on the stringer broke (after 8 years of use). I ordered a replacement and had the new one less than a week after I ordered it. Over 25 years time I have never been disappointed with Klipper USA.
