Amazon won't let me use the language this product deserves.

According to my purchase history, I bought this almost exactly 3 years ago.
According to the claims on the product description, the estimated battery life of the keyboard is also 3 years.
During the time that I've owned this piece of hot garbage, I can guarantee you that I've spent more on batteries than this hunk of useless plastic cost. I'm by no means some power user that is gaming 24/7 and putting the keyboard through constant use. In fact, I do much more work on my laptop than my desktop.
And yet, this thing chews through batteries like my dog wolfs down dog treats.
The cycle goes about like this: Put in fresh batteries. The keyboard works great for approximately a month. Then erratic behavior begins. For example, it'll just completely freeze for 10 to 30 seconds and then blurt out a bunch of nonsense letters. Maybe it will just decide to key in an endless stream of spaces until you shut it off. Take the batteries out, put fresh ones in... and everything is fine again. Oh, and those batteries that were in it? Still usable. It's just that apparently unless there is ABSOLUTELY A FULL CHARGE, this keyboard just can't even. And it will throw a temper tantrum until you put fresh ones in.
Honestly, if I could, I would sue Logitech for the battery replacement costs. Or the aggravation. Or maybe both.
And the mouse isn't much better. The batteries in it are also supposed to last quite a long time. However, my experience has been, again, only a month or two before it quits. At least it doesn't get erratic like the keyboard. It just flat quits.
Either way, Logitech's claims are absolute lies and fantasy. I honestly wouldn't be surprised if someone told me they have ties with the major battery companies for kickbacks.
The shame of it all is that when these two items actually work (rarely), they are very comfortable to use.
As is, I'm done with the aggravation. I'll be spending my money with a different company from now on. Logitech used to be a trusted brand. Now they are just an untrustworthy scam.
