Summary: The refurbished keyboard just came in. I plugged the charger into it and all it would do is light red. So I took the batteries out of a dead keyboard just like it and now it works fine. I thought that refurbished would me checked out for resell and not sold to me already broken. I would be sending it back if I did not already have the proper spare batteries. Also, the batteries inside the keyboard was miss matched and nobody caught it.
Pros: great keyboard as long as one drop of water does not touch it.
Cons: Made poorly in case of minor accidents, Apparently you take your chances with refurbished. This is my 4th replacement in 2 years due to the smallest of water spills onto it. You would think for $100 new, they would make them better. Even my $9 keyboard handles spills better.
Summary: I give this device 3 stars. It has a wonderful design and feel, but the lagging almost has me looking away from Logitech Unifying.
Pros: Wireless. I can't tell you how little I miss that keyboard wire. I really like the feel of this keyboard as well. I also have a Loigitech TK820 wireless keyboard and this k800 blows it away. The illumination I thought would be a cool feature, but since I use this keyboard at work it hasn't really been very usefull. If you game or surf in the dark this might be a great feature. Either way it doesn't take away from the functionality of the device.
Cons: I'm not sure if this is a problem with the keyboard or the unifying adapter but both my keyboards lag from time to time. The Internet seems to think it's a problem with 2.4GHz interference. Sometimes power cycling the device can make the lag disappear.
Summary: I ordered next day shipping late thurs/early Friday with rush processing and I didn't receive it until Monday. EVEN THOUGH it was just SITTING in my home town on Saturday in a locked and closed UPS store. I wish Newegg had a more clear request for Saturday or fedex delivery option. They refunded me partial shipping because it arrived after his birthday and I wouldn't have even selected next day if I had known it was never a possibility to pick it up Saturday.
Pros: Logitech- trustworthy company, innovative products with features you actually want to use. I wanted a backlit keyboard, that wasn't constantly lit up, but also not glow in the dark paint and cheap. I wanted wireless with a wired option that didn't have to be charged fully before use. This keyboard was it.
Cons: Logitech-- the first product you receive will be a brick or have some defect and the replacement will be amazing. I bought this product for my husbands birthday, with issues I'll explain below but the above statement just sums up our luck with electronics. Idk if it's Newegg or Logitech but the first bought item never arrives in full working order-especially if we are excited about receiving it or using it. The backlight didn't function properly and my husband was imm...
Summary: This is a very nice keyboard. I bought this one because my previous backlit keyboard keys were coming off due to cleaning. The angle lifts on the K800 collapse when I move the keyboard towards the monitor. I move the keyboard around a lot and this constant collapsing is unacceptable.
Summary: Had a Razor Lycosa before and probably should have gone back to the razor. Not much of a gamer anymore and thought to save a couple of dollars by buying logitec. Should have stayed with higher end keyboard manufacturer.
Pros: Form and function as expected
Cons: RF signal and wired connection has intermittent issues. Updated drivers directly from Logitech, checked battery (left plugged in), and still get intermittent letter spam/delays/.... Probably OK for intermittent use (wouldn't see intermittent issues so much).
Pros: Slim keyboard with quiet keystrokes. It uses a traditional layout, no dumb arrangement of keys. The battery life seems to be very good so far. This is being used for work, so I am on it 8 hrs a day, 5 days a week and it has been over a week so far and it is still showing 2/3 bars. I love that you can use the board as a wired as well (when charging). That way if the battery life starts to deteriorate, the keyboard will still work.
Cons: The back light is a joke. It comes on, goes off, comes on, goes off and then stays off. It has two modes of illumination, 1 being when a key is pressed and the other when your hand moves to it. Most of the time, it does not work like it is supposed to but sometimes it does. If you don't need illum. then it isn't that big of a deal. If you plan on using the computer in the dark where backlight's are handy I would look elsewhere.
Summary: Replaced dead batteries with 2100Mah low-self-discharge NiMh parts from Tenergy. Keyboard fires right up and topped off the charge in 30 minutes.
Pros: Unified RF receiver, rechargable, construction quality is quite good.
Cons: The batteries were DOA. The keyboard shipped with (2) Sanyo Eneloop 1950Mah NiMh batteries that were completely dead and unrecoverable, resulting in the bottom battery LED flashing red on a 1s constant pattern. These are pretty easy to replace, if you have some spare NiMh AAs, which is the route that I took.
