when unpacking I found that the wasd buttons were pressed down to the stop, the smaller loosening of the press is not suitable for writing and defacto even for playing, I was too lazy to advertise it so I disassembled it, I glued pieces of adhesive on both sides of the buttons to test and put thicker paper and it works with the addition of +- 2mm-3mm buttons now sound great as if they have a low stroke, which makes it easier to write, but an hour of shit and loss of warranty, not much for the price, I would see the price tag as 400-500 max, next week I will change the battery for 3 times the capacity so I wonder if the battery will last a month on a single charge, now it is max a week, slower charging but using and charging works
works, fast switching of devices, when idle the drive shuts down and saves battery
cheap design when unpacked wads buttons snimali pressed to the stop

Poor quality keyboard and mouse, uncomfortable everyday work with the keyboard - it reacts badly to keystrokes, the left button on the mouse broke within a few months.

for a long time I could not find this type, even with the help of alza assistant. MULTI DEVICE option could be more visible in filters
switching between 2 WIN PCs via BT without problems + Wireles dongle for 3PC
good price/performance ratio, maybe a bit weaker design
mac/win switch
the mouse is a bit bigger and may not fit everyone's hand, but that's more of a habit
