Critique
“The keyboard has been great but when I received it a couple keys were broken. I had to glue the inside connector back together as it had broken apart. Otherwise the keyboard has functions very well.”

“I love the keyboard! Everything was as expected but the keys are even smoother than I could have hoped for. I love the color, it matches exactly what was displayed on the website. Setup was very easy once I actually read the manual. I like that it gives you…”
