Joar, a typical tracking motor for EQ-3 telescope mounts. Good and securely packed the engine comes in a cardboard box. Unfortunately, no pocket for the battery compartment. The connector from the batteries to the controller is a little too light for my taste, but he keeps. The buttons on the controller are a bit noisy, so you get to break something while pressing almost afraid. The entire unit is, however, strongly built, may as involuntary rausgefunden fall down sometimes, and the rotation is properly uniform. No functional defects found. Gladly invested money. Thank Seben
