Relatively affordable, cost-effective.No need to say about the configuration.
Most dissatisfied
I dare not say the quality is good.I changed the two because the ESC key is not sensitive.The third is that I use this now. There is a problem with the USB interface. Sometimes it works well, sometimes it doesn't.There is also the up, down, left and right keys of the keypad. When typing, you want to skip the position and cannot see the cursor. I don't know whether this is a problem with the input method or the system.In short, many problems are still being explored....
