Angle at which the watch sits is too low, so it doesnt always make the rotor turn, plus
Not only does is not always make the watch rotor turn because the watch sits at too low of an angle for the rotor to spin, it doesnt have a specified turns/per/day on the settings which is how pretty much all reputable watch manufacturers report rotor winding requirements for the use of watch winders. Also, the watch pillow adjustments were either too loose of too tight on some of my watches. A better design is like what you find in the Versa watch winder; they use a spring/loaded cushion for a perfect fit and constant tension to hold the watch securely, not to mention they wind the watch in a vertical position so the rotor is going to turn more reliably.
On the positive side, it was nice a quiet, but some good that is if its not well designed. Unfortunately, not recommended.
Sidenote: Most watchmakers dont recommend using watch winders because they will wear the watch movement unnecessarily. Just wear the watch regularly in rotation with your other watches, and when you set it aside, if it runs out of power and stops thats okay, let the movement rest between wearings and reset the day/date if thats important to you (doesnt take long to do with a quick/set date) .
On a further note, its not recommended to regularly manually wind most automatics because they were not designed for that; their gears are not as durable as a manual/only winding watch. Better to do maybe a few winds to get it going and let the rotor do the rest as long as youre not sedentary. Good for its value.
