I really wish I had done more research here before I purchased, but I needed a good keyboard alternative and it looked perfect for my needs.
It arrived in a week or so and upon unboxing and setup the right side of the keyboard didn't power up at all. Jumped through all the testing hoops myself and indeed it seems like an issue with the left side of keyboard and no data or power coming out of the USB link port (that you use to attach the right half of the board).
Opened a ticket with support, and been going back and forth for a week now. All the lame excuses, try other cables, plug it in direct, make a video that shows you doing this, etc. So I made a video that clearly demonstrates the issue. Then they said they couldn't view it (my server logs said otherwise) and asked me to post it elsewhere. Two more video posts and now they have dropped that tactic and have circled back to saying "Can you please try it again with the included USB cables" which I clearly used along with another pair of actual quality USB cables in the video that I sent.
I really wish I didn't do that late night purchase before I researched them. It's a shame as the keys feel great on this board -- even though it looks like Hello Kitty (they also didn't really say anything around this either LOL, it was described as Blue and White, no mention of the flowers and candies and donuts on all the keycaps).
Should I just be calling Visa and doing a chargeback with these jokers? It's been a week going back and forth with support now and we seem to be back at script page 1 to try and avoid replacing the defective hardware ...
