-Let's talk first about the design. It's a nice shiny metal that is polished and smooth with no sharp edges. The placement of the cutouts could be slightly different to align properly, but it's no big deal, every person is built differently anyway. The lock mechanism is maybe a bit too big, producing a bulge under clothes. The key itself is a clever design, but is a bit too loose, giving some play between the ring and cage, resulting in small pinching if not placed well.-The material is nice but can peel a bit and leave some flakes on the skin, something that can be improved in future models. Of course, it's metal, so be sure to warm it before if you don't want to feel cold first!-The weight is decent, it's a metal cage so expect to feel it, which is a good point!-The lock is good, and comes with two keys, but too bad it's too bulky.Overall it's a decent beginner item, not too big nor small, decent weight if you're into these heavier models. Its price is also a compelling argument compared to other brands offerings plastic models for way more.I also want to underline that the customer service is reactive and dedicated to helping you, and it gives additional points for sure!
