UPDATE: After 4 months, one of the motors on one of the 3 winders I bought went out. I contacted the company, sent a video, and they mailed a replacement out the SAME DAY saying that they continue to improve the motors. In addition to the below 5-star review, its very encouraging customer service. The warranty is 3 years. All watch winders apparently experience motor failures. I was expecting to have to mail it back in, fill a warranty claim, etc. Nope! Emailed a video and in 3 hours got a new one mailed. Amazing.
Mozsly has the smallest profile/size of double watch winders AND you can connect them to use the winders in parallel. That means that you can easily create your own 6-watch winder to fit any space.
I needed a 6 watch winder for my safe. But none of the other brands would fit. They were big and bulky. So instead I bought 3 Mozsly. I connected the primary one via the screw hole in the back of the safe, and the other 2 connected. The amazing thing is that I still have plenty of room for other things in the safe.
Having the twist off windows isnt a downside, its a huge perk since it allows these devices to fit into a smaller space.
Ive owned these for over a week, but the motors appear great. The company confirmed the extended warranty. They look gorgeous (its a shame theyre in my safe).
When the devices run in parallel, they all activate at the same time, which is neat. The devices that need extra rotation continue to run.
I highly recommend buying this winder over any other if youre looking to create a DIY watch winder safe. Those run into thousands of dollars, and if a motor fails, youre screwed. Most of the watch winder safes dont even screw down or into the wall. Here, even if a Mozsly motor stops after 4 years, I can just replace that individual unit. I have no reason to believe the motor will stop, but that was my largest concern.
Oh - and Mozsly is SILENT. I didnt need mine to be silent since its in a safe, but its much quieter than the other brand I have. Really nice job.
In summary, build your own watch winder safe and use Mozsly for maximum storage. I believe they even have 1-watch winders if you need to mix and match.
