The Tecnifibre machines are built well. Compared to the Baiardo, Yonex, and Babolat machines, Tecnifibre machines are a bit awkward to string on. The mounting is sturdy, but the k side supports get in the way. The clamps take real effort to open and close. The button to activate the tension head is not on the puller; instead it is on the base of the machine.
There are some "quirks" - but the reliability is a big issue - here in Houston both shops that have the Wilson have had issues with the motors and one was already replaced by Wilson and it was less than 6 mos old.
