a model with serious flaws
3 June 2025 
after 3 months of use, the keys randomly started pressing on their own, and upon unpacking the keyboard, I noticed that the letter "x" doesn't press well! The quality is worse than a keyboard for 200 UAH.
backlight on 3+
stopped working and started pressing buttons randomly.
