Sturdy and well made
Good quality and sturdy, they fit to the motor spindle and stay there. Comes supplied with grub screws and an tool for tightening them up

Perfect fit
These adapters are perfect for attaching to small motors with 6mm spindles with two grub screws to secure them a nice solid fit

Nicely made
Good value for money. The only problem was that the very small grub screws came out during transit, and then came out of the plastic bag that contained the flags. Difficult to subsequently find.

Overpriced
Good product, overpriced a little bit

Nicely made.
I use these from an electric motor to a gear on my model fairground rides. Fit the motor axle nicely and are concentric. Holes for bolting through.

Check you have the right size, these are quite small.
Good quality with grub screws to tighten onto a small drive shaft, I used these to attach a pulley wheel to a small 12v motor and they worked really well. not very big so check your sizing before you buy.

Not complete
Received the 4x couplings and an Allen key - But only one grub screw though and so not 5 stars. I hope I have some laying around...
