Burned twice by Chihiros product.
I purchased a $230 WRGB II 600 LED - the green light overheats. $81 to ship back.
This came with the Doctor Mate $50 which doesn't work at all. I got $0 refund according to Aliexpress when I filed a dispute. No reason given.
According to Chichiros, if there's no local distributor, buy at your own risk.
