My husband and I have a few watches that require movement to charge the battery and always seem to find that they're dead a lot because we don't move them around like we should. Since getting this watch winder, none of our watches have a dead battery anymore. Using this watch winder is a lot easier than what it really looks like. The instructions are really easy to follow along with when we first tried using this. Even with the different sized watches that we have, they all fit in each holder with no issues. Even with moving around, we have not had any issues with them falling off while they're moving around. The dials are really easy to use and can be set to go in any direction too. Each dial goes to either side of the watch winder so if we only need to use one side, we can just turn that dial for that one side. While our watches are moving, there really is no noise that this winder makes. There are even times that I forget I have it on until I see the watches moving. Whisper quite and so easy to use!Quiet and we'll builtI have 4 automatic watches and this winder seemed perfect; stylish and quiet, but in my experience this product has no "stamina" - I've had two of these units now and both have had one of the two motors stop working; the first after only a week. Amazon quickly replaced that defective winder. The second unit has lasted 3 months, but again one motor stopped working so only 2 of 4 watches rotate and stay wound. The bad news for me is the return period is over. Not buying another one, guess I'll revert to the 'ol thumb-index finger mechanism.**Update: 6/2/22**So, it appears my enthusiasm for these lower cost winders was a bit premature and I have reduced my rating to three stars. While this unit still adequately functions for my needs, the individual turntable rotational speed tends to be inconsistent if only one heavier weight watch is mounted on a turntable. The turntable gives the appearance of being out of balance and struggles to complete a rotation. I placed a diver style watch weighing around 160 g on the left turntable and it immediately looked like it was trying to drag a boulder up a hill. Once I placed another similarly weighted watch in the second slot, it was fine but the fact it has to be balanced is a concern as there will be instances where I actually wear one of the watches...**End of update.**Original review:As a watch enthusiast and also a vine program participant with an embarrassing lack of impulse control, I've added a number of low end automatic watches to my collection, to the point the number of automatics in my possession far exceeded available slots on the watch winders I owned. In the main, most of these angled carousel winders had too many deficiencies to meet my requirements, let alone meet the TPD specifications of some higher tier watch makers. Notwithstanding those considerations, the Flint 4 slot winders may well be as good as one is likely to find with more economical units.I consider the Flint 4 slot winders to be of quality construction and above average performance for the price point. While it has a few deficiencies often found with these lower end winders, based on my experience with them (I liked the first one enough to acquire a second four slotter) thus far I don't think many competitive 4 slot units in the sub $200 range are going to equal or surpass it, either in terms of build quality, versatility of mode options, quiet operation or durability. According promotional information, it is driven by two Mabuchi motors, a widely respected driving source found in a healthy proportion of lower to mid-priced watch winders. As is common with that motor, this device is commendably quiet and smooth in operation. I have the same motor in a couple of other winders and it has proven highly dependable, accepting I don't have any of them operating 24/7.It also features a choice of power options, either AC power or battery. For the latter it requires two "D" cell batteries, which in my case powered the two Mabuchi motor driven turnstiles for approximately two weeks when set to rotational mode '4.' While not specifically stated with any of the documentation, I do not believe the batteries should be left in place when the winder is on AC power as with other units I have from other distributors/manufacturers it is noted the winder could be damaged by doing so.The medium density fiberboard constructed box is covered with a black and gray houndstooth patterned shiny finish polymer sheet covering and features of acrylic glass display forward opening top. As noted above it is appreciably quiet in operation and there is a convenient auto stop mechanism when the top is opened. The watch box is lockable and the package includes a skeleton styled key. The back of the winder houses the battery compartment as well as independent activation switches for each of the two watch turntables. The winder also has a unit power switch and another for the background lighting.The more or less horizontal orientation of the memory foam pillow cushion slots on this model facilitates accommodation of larger cased watches side by side on one turnstile without the cases or crowns of one watch potentially damaging the other. I have included a photo of two larger case models mounted side by side (the displayed watches on left turntable are not automatic but only mounted for demonstration purposes - I don't own any automatics of that immense -around 48mm each - size.) NONE of these lower price watch winder sellers seem to comprehend cycle time isn't the only specification for automatics and many users need more options to determine the optimal settings for their watches. However, grading on the curve this one impresses me as a much better than most at this price point.
