These being my first time ever seeing (let alone wearing) a pair of leather wrist restraints, I can't really compare them to other products, but I can tell you this... These is a true joy to wear and the feeling of domination from them is just amazing.
They are very well built, strong, sturdy, and despite not having weights added inside them, they do have a bit of weight to them. The fleece lining makes them comfortable for wearing for long duration bondage (I would imagine, without it, the leather would dig into your skin). A single D ring on each restraint is secured well and is nice and chunky, adding to the domineering feel from them.
However, the real joy is to be had once your restrained in them. Unlike rope where you have some freedom to move, these leather restraints offer almost none. You feel completely bound by them, unable to get free, and they give the impression that you are your Sir's meat, like it or not :).
Don't let the fleece lining fool you, these are top notch leather restraints. They are very well built, offer an amazing feeling of domination and are very well priced. Buy them, you won't regret it.
