I purchased this directly from Vilros and have to be honest. I do not think it is worth what I paid. My biggest issue is with lack of audio speakers. I can understand the monitor size as well as the lack of an on board battery. For around the $250 I paid, I could buy a full fleged laptop to put a Linux based operation system on. I am fairly disappointed in the bang for my buck. Just my opinion. I love the Pi concept but this was not a reasonable price for what I got. Silly me.
