Summary: I have 3 of these now. The first was about a year ago, and performed well enough that I just got 2 more for other computers. If you have a light typing touch, you may not notice how flimsy the bottom/deck plastic is; if you pound the keyboard, you will.
Pros: Key mechanisms appear to be well-made. White characters on keys are holding up well.
Cons: Weak, flimsy pop-up "legs." Deck is flimsy - especially noticeable at and near spacebar. Not bad enough to lose an "egg."
Summary: I have yet to find out how returns work. I'll be shocked if I get replacement parts... I think I'll just buy a little more expensive keyboard and mouse combo. Although it could have been an issue with packaging or shipping. Very hard to tell.
Pros: Logitech is a good name and the product is cheap
Cons: I purchased three of these and one had a broken mouse. One of the keyboards had a key that didn't work (Didn't find out for two days.) and I haven't opened the third yet.
Pros: It works on my Mac. some of the buttons on top are inoperable, but I don't really mind. Its a low budget item and delivers well. I don't have the mouse on a mousepad right now, and it has done very well so far. Impressed.
Cons: a bit cheap feeling, but you should expect that with the price tag.
Cons: I used to love Logitech keyboards. I've got 25+ in my office. But the last 2 I got were both defective (months apart so not the same lot). One was DOA. The other had inactive keys. If you buy one, keep in mind there is no Newegg customer service. YOU must mail the product back at your own expense...
Summary: I replaced the mouse for something with easily adjustable DPI (for gaming purposes), but from my limited experience with it, I was completely satisfied.
Pros: Focusing on the keyboard: It really does deliver. Works very nicely, plug and play super smooth, and I can testify to the spill-resistance of it. I spilled about half a coke across this keyboard, and the liquid really did just sit between the keys, and barely leaked any (from what I could tell), ...
