I will say I got this mainly for its retro styling. It looks like a very old school dumb terminal keyboard. And lifting it up, it even has that feel of a weighty old time terminal keyboard. I love that it's wireless, but it's kind of a pity that it didn't come with a USB charging cable that was coiled and thick like the old telephone handset style of cable the dumb terminals connected with. And then, when you plug it in or hit the power key, the black and white background becomes a playground for a rainbow of colors! How cool is that? (Until the battery saving sleep mode kicks in so you don't have to charge unnecessarily.)
I'm not a big gamer, wouldn't know how to measure response times, and don't bother learning how to program shortcuts. I do appreciate the full sized numeric keypad.
With all of that lighting, I do wish they would've made the key caps translucent so you had a light up effect for readability. Also, upon plugging it in, I saw it was at a 90% charge. Leaving it plugged in, it soon jumped fully 10% in a single bound. I then unplugged it, and when I next turned it on...it was back down to 90% again. So, I guess a full charge is elusive and I have questions about its charge meter.
Overall, I would say that this is worth the price and I'm happy that I have it.
