I have the Flex 740 for over 4 years. We string about 25 racquets a month. Every parts is good. The string job is good. We do not have any problem. I want to upgrade to the electronic machine. A few days ago I went to the Gardena warehouse to pick up the Combo 3800. Victor even showed me how to operate. The tension pull is constant and precise. I love this machine.
