Includes 1 review aggregated from around the web.

Owners are mixed, based on a small number of reports. A German forum thread tells of a new unit that began trembling badly after two flights, and another owner found one of four unused units vibrating at first power-up, which a poster says usually points to a faulty potentiometer. Glider pilots otherwise trust the brand for aileron and flap work, with fewer problems than most. No widespread failure pattern was reported.
