As noted in my prior review, after 2.5 months of repeatedly trying to exercise the company's return policy, I have gotten exactly one response, which said basically, "Sorry, we're really busy right now". I'm going to have to resell these items on my own to recoup my cost.
If you are going to purchase, do it through a reseller with a known return process like Amazon. Don't buy direct if you have any though of needing support.
