Opened the box, saw the instructions written on the inside cover of the box (nice simple pictures), plugged it in and it worked. No software needed to install, no charging, just worked. The keyboard can work with minimal inside light (i opened it at night).
The feel and sound of the keyboard is similar to a macbook keyboard. It has a little curve in the keys though so it’s easier to feel for the center of the key. I like the keypad and the Insert/Home/Page Up key section. I’m a programmer and I’m used to using the Home/End buttons to get to the end or start of a line or page while typing.
My desktop is on the ground below my wooden desk and the receiver plugs into the back of my desktop. It’s a good 3 feet away from the keyboard with the desk in the way. The keyboard works fine with this setup. It’s a lot better than the old mini receiver Logitech used to have where it needed to be on the desk for it to work good.
K750 Solar Keyboard is green in more ways than one. It doesn’t have batteries of course. It also doesn’t have loose paper instructions. They write all instructions and info on the inside of the box. If you need more instructions, they give a website to go to to get a pdf.
My only gripe is that it doesn’t work with a mac. It has to be Windows as stated on the box.
I think the Logitech Wireless Solar Keyboard K750 is the best keyboard I ever bought. It seems to let me type faster once I got used to it.
