So this is the second Genki adapter I've received. The first adapter I got was dead when I got it and didn't work at all when I plugged it in. Luckily Revain sent me a replacement the next day. I've been using it about 3 or 4 days a week or so for the past few months and when I plugged it in today it fell apart completely. I've emailed Genki to see if I have any options, but as of this writing I haven't received a response. The build quality of this product is not what I expected from something this expensive.
