I have to concur on the Aldans. I was one of the early customers (victims) when I tested them out before I would resell them. After losing 3 sets or rears in a row, I sent them back for a refund, only to get boned with a ludicris $300 restocking fee. I was so happy to get rid of them, I didnt even care at the time.
I dont know what/if they changed anything at the time (they stated they had for set #3), or if they have since, but after having one of them apart (curiosity, blown out anyway) they are built lke absolute garbage, and I will never purchase another set to even evaluate them.
