I have "Bertha" (4x6) and love it. I'm patiently waiting for 2x3's to get back in stock to buy another smaller one. Oddly, though the process to buy was problematic. I never received an emailed receipt or shipping information, it just showed up one day. No receipt in the box. Also, at one point the SSL on the site was bad.

All of this to say that the product is amazing, but they are still working out the kinks... the kinks mainly (to me, at least) being customer service related. I'm sure that is just a growth issue, though, and will be taken care of in time.
