"Doesn't Hold a Charge"0.5 starson by Hydrictis
Pros: This keyboard has a nice weight to it, and feel sturdy under your hands. It is large enough to support a full array of keys without it feeling too crowded and the chicklet buttons give it a slim profile.
Cons: The keyboard stopped holding a charge after 2 months. I got Logitech to send back a refurbished one to replace it but that one failed only a month later. I'm not the only one with this problem, there are many threads on their support forums about it.
Summary: Save yourself some money and go with a different keyboard. So many people are having the same problems about this keyboard not holding charges, it's clearly a massive issue. Don't press your luck thinking you'll get a good one. If you need a keyboard that will last you months, and even over a year on a single charge, then there are many models (some sold by Logitech) that last quite a while on batteries.
If you're environmentally conscious, then get rechargeable batteries like I did.
