Machine is very easy to learn, but make and investment in starting clamp with it. Practice is needed though to become proficient, especially with certain racquets that have that have string patterns with covered grommet holes.

First time stringer. I read newbies took up to 3 hours to string the first time. Took me longer but mainly due to what I now view as basic instructions lacking in the how to use manual. This is a crank style machine and there weren't any videos on the web on how to use. The assembly instructions were for an older version of the machine and some parts were different. With the help of someone who has strung before I figured it out. He told me the racket I used for my first stringing job wasn't the easiest to figure out but agreed that the instructions lacked information. After we finished he used his tension measuring device and the tension was spot on per the stringer settings. After all is said and done the machine works well and we are happy with the purchase. I think it would be helpful if Gamma sent along a tutorial video specific to the machine.
