Loved it!

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 the option if you want to cnnect it via USB or if you want to connect it completely Bluetooth.
