Awesome keyboard. I observed only one minor nuisance, after the keyboard goes to sleep when awaken by typing it sends backspace codes for the initial keys. I don't know if it's the keyboard (in Bluetooth mode) or something with my computer. I didn't have time to look for the root cause, so far I quickly adapted to a habit to use modifier keys to wake up the keyboard before I start typing after a long pause.
The function of the product is normal. But there are 4-5 keycaps with dye on them. Alcohol does not erase it. Please refer to it when you buy it. I bought a keyboard for the first time, and it's a shame.
