We already had Velcro cuffs and we noticed that they came loose very quickly. When we heard there was a version with a strap, we wanted to test it. We also liked the over-the-door feature, because it is different than what you'd normally use.
The packaging
The packaging looked nice. You get a very sturdy black box that closes with magnets. The handcuffs are packed in a separate plastic bag. All in all, it looks really sleek and provocative.
Look
The handcuffs look very sturdy and the straps have a lot of adjustable rings (8). The material feels very nice, it's just a little stiff. Of course that may lessen the more you use them. There's a lock on the cuffs to attach them to the door holders. There are weights on the door holders so that they stay on the door. There is also a large ring to attach the handcuffs.
Use
The handcuffs are really easy to use. You put the two door holders over the edge of the door and close the door. The weights then hang on the other side of the door and make it so that you can't move your hands. You put the handcuffs on and make them as tight as necessary with the strap. Then attach the handcuffs to the rings that are attached to the door holders. If all goes well you are now firmly stuck in place.
The conclusion
We think they're really nice handcuffs. They stay in place well and they're sturdy. It's exactly what we were looking for. It's nice that you can attach them to the door, so you can try different positions than with the usual bed cuffs. We definitely recommend them.
