Have not strung racquets in 30 plus years. Got tired of people screwing up string jobs so finally started again with this gem. Works like a charm, no more botched string jobs. Recommend joining USRSA for access to Stringers Digest.
Not a bad machine, easy to use once you figure out how to string a racquet. The book it comes with has no real details it is just general terms. I had to call a few buddies to help me. After a few mess ups I have strung enough racquets and including my own to pay for itself.
