I have only used 3 sizes so far but they all fit my bits well and ran with minimal vibration. As good as the ones that came with my cnc router. Nothing special about them except the price but I'm happy with them.

I tested the 8 mm collet in a high quality router motor that I have in a router lift. It looks as good as the collets that came with my router motor. The bit ran with minimal vibration and cut well. I'm not sure if I will use all the collets that came in the order, but I like having the choices of sizes so I can order other size bits in the future.
