I couldn't be happier! I've worn mine for a week straight, and it has proven comfortable and resilient through miles of jogging, rucking, dog walking, and drumming. I only take mine off to charge my Galaxy 7 Watch.
The cuff gives the OEM charger ample access and makes charging a breeze. I do have trouble with a 3rd party charging battery, as the cuff has molded *perfectly* to the curve of my (admittedly tiny) wrist.
The cuff design also heads off a complaint I've read about the green sensor lights of the watch. Those lights are not visible, day or night, until I take off my cuff.
Pay attention to the diagram about string bar to spring bar and the lug width. Expect to get exactly what you ask for, so measure twice!
For me this was pretty much a one-and-done installation. My watch is in its forever home. If you want to cchange yours out, you'll need to get handy with the included lug tool and have a good place to store the lugs. (It comes with 3, so you'll have a spare)
