Saw this on clearance at my local Kmart for $23 down from $39. Have used one before, and it was genuinely not bad at all, provided you're ok with the clickity-clack from the blue switches. Had a quick look at stock levels online and there appears to be plenty around (at least in WA) at time of posting. Don't expect it to be up to scratch with your Logitech, Corsair or DAS keyboard and you'll be right!
Quick edit, because it doesn't seem to be written anywhere: You can not change the colors of the keys. You can only either turn the lights off, make them flash in different patterns or keep them static.
