Half the keys didn't work

I bought this for my daughter as a Christmas gift. It arrived on time and was in new condition, but only the top half of the keypad works. You can't use the letters on the bottom row. Returning it now.

Only half of the keys worked rendering the keyboard completely useless. Wasnt able to connect to my android device because the Enter key work necessary for entering Bluetooth password. Once I connected my iOS device I could test out the keys. Random keys did and didn't not work.

So far, I am impressed. Except for the fact that 6 keys don't work at all. Tried typing my name, and it left off the A and the L. Hell of a thing. Selective typing won't solve this problem. Logitech was ZERO help with the problem. Amazon is taking it back, but I am scared to see what the second attempt will show. If it works, awesome.. then I will revise my review.

I got this as a gift for my elderly parents; right out of the box several of the keys didn't work. I replaced it with a new one for them, and again some of the keys don't work. They use it anyway, but are limited in their ability to use some keys.

I've ordered already 3 of these keyboard from different sellers and many of the keys were not working at all!  with this one I had some problems ONLY with space key, it was oversensitive, it would seems that you press it all the time even if you would only lift the laptop, not touching the key at all! Had to do some adjustments with the wire underneath it so it works ok not but it doesn't give you that click sound. Seems like it sits too deep now but hey! at least it's working now! :P

When the key board came it did not work. Luckily I had an IT guy who had similar issue I n the past and knew how to do a reboot on it. Also the keys aren't very sensitive and sometimes I have to really give it a good peck to make the number keys work. But I get lots of compliments on it.

Its a great keyboard but mine came and for some reason my A key isn't working very well, all the other keys are working just fine except for my a key so I was wondering if theres any way of fixing this.

ok, so the keyboard is beautiful. i love the blue led lights and the fact that it has an on/off switch. problem is that some of the buttons on the right don't work. 4, 8, 6, 2, and 0. also one of the arrow keys doesnt work. i thought maybe it was numb lock but nope. i tried using a different port. i tried going online to see if anyone had any trouble shooting tips but i couldn't find anythin. i use the numbers keypad a lot for work so im sorry to say that im returning the keyboard.

I received my keyboard less than a week ago, and I already have to return it. Every key on it works perfectly, except the bottom row of letters. It's the weirdest thing. I press them, and nothing. Every other key is fine. On the plus side, Amazon is great with returns.

Seven keys didn't work. I'm afraid that if I buy a new one I'll be just as disappointed.

The mouse is great, but the keybord didn't work.  Only the Q, W,A and S are ok.  Don't Buy It!

I love the look and functionality of this case, but some of the keys don't work so I'm sending it back. I will try one more time with a new case.

Second day with computer a handful of keys became unresponsive. They worked intermittently but I will be returning if problem persists.
