The nuts themselves seem to be fine, but I haven't received all of them yet. There were only 20 in the box and there should have been 32 so I missed 4. Now every wheel is missing a nut and I have to spend more money. The box arrived undamaged with no signs of tampering, although none of the nuts were in the small foam retainer they just dangled loosely in the box. I think the fault is Revains, not the manufacturer, but still lame. Value for money would be good if I got everything I paid for and not if I had to buy 2 sets to get 1.
