A cheap keyboard with all the consequences, I've been using it for one day and it's still unusual.
Worked for several months and broke.
Do not buy under any circumstances!
Pros
Inexpensive mechanics on green switches.
Cons
Very noisy, neighbors knock on the radiator at night. You can not change the backlight of the keys, 3 backlight modes in total. Thin wire. If you run your hand over the entire keyboard from above, it makes noise like a mining farm.
