Fairly good quality, but shipping takes 8 weeks (ouch). The best price and shipping is free. If you cannot wait 2 months you may want choose something else.

Waited about 8 weeks for delivery. And had to return because the pins keep falling out.

While both may hold a 10 lb weight, one does not tighten to hold a 25 lb plate Probably will not use on anything but a light weight dumbbell.Recommend for lightweight use

Does not fit on bars and a pin fell out.
