Garbage!  The MK470 is nothing short of GARBAGE.
Horrible technology, crappy design and $hitty capability.

"Save your money if you're thinking buy this keyboard." in the barely case where you are going to buy it for gaming (of course that is not his objective of this device)

The keyboard works well but for gaming , hell no, specifically the E-sports, sometimes when i use several keys, the keyboards comes laggy (a bit or to much), considering that the usb port is connected to the motherboard (a better response time), reducing the timelapse between the lag events versus a notebook (a con is the data bottleneck of the
keyboard, because in the "lag events" the only keyboard became laggy not at all with the mouse, and why i bought this combo, because at that time i did't had to much money like now. (pd: when i usually use the keyboard i don't have a Bluetooth device on).

Save your money if you're thinking buy this keyboard.

Any ideea why Logitech has stopped selling US ANSI English layout keyboards in Europe?
I understand they are only providing the ISO layout with vertical enter and smaller left shift to fit an extra key.

i had been using this combo set for months now. no issues. its always ready to work. and the mouse clicks remains whisper quiet even after daily use after 6 months now. only needed to change the batteries once.
