EfaithtekAutomatic Single Watch Winder with Japanese Quiet Motor，AC Adapter or Battery Powered

Does what it is supposed to do - it keeps my watch running. And best of all, it is completely silent. Works for me!

Simple to use and good quality

Having been a discerning collector of fine timepieces for many years, I recently acquired the Efaithtek Single Watch Automatic Winder, with high expectations of its performance. My initial experience with this device was nothing short of remarkable. For the first month, it functioned flawlessly, maintaining my watch's precision with grace and reliability. The winder operated smoothly on battery power, which I exclusively utilized, and I found it to be a commendable addition to my collection.However, my satisfaction was unfortunately short-lived. After a mere month of use, the winder inexplicably ceased to operate. I promptly replaced the batteries, hoping it would resolve the issue, and while the winder did resume functioning, this resurgence was fleeting—lasting only a week.Following the detailed instructions provided, I then attempted to use the winder via the electric connector, sans batteries, anticipating a return to its former glory. Regrettably, this attempt proved futile, as the winder has not worked properly since that moment. In a bizarre twist, it occasionally moves on its own—without any batteries or electricity—albeit at an incredibly sluggish pace, as if it were a ghost of its former self.In conclusion, while the Efaithtek Single Watch Automatic Winder initially performed admirably, its subsequent decline into erratic behavior has been profoundly disappointing. For a connoisseur of horology, such unpredictability is simply unacceptable. I had hoped this winder would serve as a reliable steward for my cherished timepiece, but it has ultimately failed to meet even the most basic expectations of dependability.

Works well, battery for travelling and plug in for the house!Great value

I've been using this auto winder for 6 months and I'm pretty happy with it. It looks nice on the dresser with my watch spinning around every so often. My watch will still run out of juice if sitting in the auto winder for a few weeks, so I recommend fully winding your watch manually before storing it for long periods. The winder ate a set of batteries in about a week so plan to have it plugged in. It is virtually silent so it can be placed anywhere.

Jeweler wanted over $300 for similar. Just as nice. Happy

Works great

it stopped working after a couple of months, changed battery and it's not rotating.
