I was a little sceptical about magnetic straps but I've been proven wrong.
The quick realise pins make swap outs so easy , the coating has already survived a scrap getting luggage out the car without a blemish.

The magnet holds very well and it's surprisingly strong for it's size regardless of garment worn it's held well.

The only risk I guess is if you catch that magnetic part you are at the mercy of the strap magnet catching quickly to hold your watch.

The mesh is very smooth on the skin and plenty of them ,it's not to thick ,suits the watch style and it molds around every wrist shape easily.
