I was "lucky" enough to receive one...
... although I was expecting two. For those not in the know, RCL emailed the backers offering a "Blankety-blank" unit with just a handful of games (instead of the 1000 promised) as a means of getting their hands on a unit "early". Bearing in mind I figured this was probably the only chance I would ever have of seeing one I elected to receive my units "blank" and install my own choice of games via the microSD card route.
The unit I have received arrived scratched, has appalling controls that are unresponsive and hard to use and is further tarnished by buggy software. Turning the screen brightness down introduces flicker and an odd interlacing anomaly. Sometimes it doesn't want to turn on at all unless I plug it in to recharge, then you can't turn the unit off and if the brightness is all the way up the battery takes forever to recharge (if at all - I haven't left it on to see if it ever charges completely).
No cables, manuals or adequate packaging for that matter were supplied. Not even a photocopied A4 sheet describing how to load games onto it were included. I consider it to be a real slap in the face to the backers who actually receive one now since it was only ever going to be the love and nostalgia of the retro community that made something so niche work in the first place. It is no wonder so many are already appearing on ebay and no doubt selling for their rarity and novelty value.
