they're decent stands for the money
Just make sure you assemble them straight away - I bought 4 and 2 of them were faulty (holes didn't match up)
Managed to make 3 good ones out of the bits and swapped the leftovers for another one
and they only really work on the front wheel with 20" bikes, otherwise the hoop bit makes contact with the hub (works fine for my bikes but the NS one has a 2.1 tyre on it which doesn't fit) Of course a hammer may be helpful to 'modify' it
