Query: Bought 4, only the first one worked

I have attempted to get 4 Cieva frames working. The first one for my mother-in-law worked great. The second, for my mother was DOA - we sent it back. The third for my Dad, required tech support, that was useless, we waited until I visited and the thing was dead at that time. The forth for my Mom is still in the box, she is afraid to plug it in. This is a nice technology in concept. In practice, it is only for techies. I'd advise finding a better gift - or use paper prints. There is less frustration and cost involved.
