Looks good in the package. I like that it comes with a washer as well as the cone nut with a flange.

Gute Qualitaet, fr 4mm Motorwellen (nicht etwa M4, wie in der berschrift steht). Was mir nicht gefllt: wenn schon mehr als eine Madenschraube-und die im Winkel von ca.60 angeordnet, dann sollten es schon 3 und nicht 2 Schrauben sein.

The treads for the 2 set screws (grub screws) are very sloppy so the set screws jumps the threads before it can be tightened properly. Also the set screws are much shorter than the length of the threads, making the force on the active threads double. These are useless and a waste of money.

I tried this as a replacement for the normal gripper collets because those gave a bit of unbalance. Unfortunately these made it worse, but perhaps it was me not using them right. There are only two grub screws and they are not located oposite of eachother. This, in my opinion, causes it to go off center when you tighten it down.

Great product, I wish the treads were just a little longer for thicker propellers.

Great thing for that price :-D I would pay 4 USD in CZ for similar think with similar quality. If you buy propellers on HC, buy adapters there. Fits better than adapters in CZ.
