My first set broke too Cain way to easy...They just are as durable as OG wheel companies like proline, aka, etc..my white dish wheel on left is from recent order, and actual wheel with spokes is from first order over a year ago.
I am not doing 10foot jumps or anything crazy at all, nor gunning it over jumps and seeing how much air I can get this damage is just from a small local track. With legit wheels I never have cracked one.
