This is my second one and I have been impressed with the units from the moment they arrived quickly. The packaging of the winder in a "box within a box" insures that it doesn't arrive with any damage, and the ease of use and clear instructions are a plus. This is important because each of the 4 winder motors has its own set of controls, and some of my watches require settings different from the others. The motors are quiet and smooth and their workings feel more solid than other average priced winders I have purchased. The workmanship of the case itself is solid and attractive. I am very pleased with this product so far...I say "so far" because full judgement will have to be postponed until I see how long the motors last before frizzing out.
