3 out of the 4 hard drive enclosures I bought recently from OWC were faulty.
I've just had to pay expensive return shipping to them and OWC will not refund me for it.
I've
never had to pay to return defective goods that a supplier has sent me.
OWC say that if they send you the wrong goods then they'll pay for return shipping, but if the goods arrive smashed to bits or not working at all, it's your problem and you have to pay to get them back to OWC.
I won't buy anything from OWC again having been stung by this unfair policy. They've lost a customer for life and I'll advise my clients and friends not to use them in future
