3.0 out of 5 stars Good HTPC keyboard with a few major flaws Jan. 5 2013
Verified Purchase
Summary: Good HTPC keyboard for limited-time usage. It's best features are its range and touchpad, the 2 only reasons I bought this keyboard (and the only reasons I'm not returning it). Keep this purpose in mind, it is NOT meant as a regular-use keyboard. It's flaws would annoy you to no end if you tried to use it as a regular-use one.

- lightweight
- great range, even with some interfering objects b/w the receiver and keyboard
- on/off switch
- arrow keys are not compacted
- no proprietary battery (AAs are easy and cheap to replace)
- touchpad

- TOO compact
- commonly used keys (specifically backspace, enter, and right shift) are WAY too small
- key depth a bit too deep
- touchpad could be a bit taller
- touchpad buttons are a bit too stiff
- native touchpad sensitivity is a bit too sensitive

Explanation of cons:
As always, I think it's important to justify the cons, otherwise they're not worth listing. First, the keyboard is actually TOO compact. It could easily be at least an extra 25% bigger in width and length and still be considered compact. It's current size makes it feel very cramped to comfortably type on for more than a few seconds at a time. And unless you're a petite woman or smaller-framed guy, it's small size makes it sit awkwardly on your lap. Plus, the extra space would help solve some of the issues with my 2nd con.

My 2nd con, commonly used keys are WAY too small, specifically the backspace, enter, and right shift key. I can't even count how many times I've accidentally hit the = key when going to hit backspace, ' key when going to hit enter, and the up arrow when going to press the right shift.

2.0 out of 5 stars This fish was bad enough to throw back Oct. 29 2013
By kevinmcl TOP 500 REVIEWER
I agree with almost everything that "home techie" said in his/her (?) review.
But since I actually bought mine to use for extended typing and "mousing", I was much more disappointed than that reviewer and therefore can't give the device more than two stars.

I had mine for several days, and they were painful days.

See my review of a Logitech tk820 for a comparison of the k400 against the keyboard-trackpad combo that I bought and like.

The tk400 feels cheap... which is consistent with its looks.
Even the supplied batteries were cheap no-names, compared with the four Duracells installed in the tk820.

As other reviewers note, the keyboard portion is painfully narrow for use by a full-size human, with full-size hands, and I was getting soreness in places it should not be. The tiny format did indeed have several frequently-used keys badly located and small, which contributed to an endless stream of typing errors.
The trackpad felt rough and crude compared with the silky smoothness of the tk820 (or an Apple product). At times it seemed too sensitive, and registered the merest touch as a tap, which meant I was constantly undoing things I hadn't meant to do - thank goodness for [Ctrl][Z].

On the other hand, I think the k400 might have had some kind of power-save algorithm that caused it to sleep after a few seconds of inactivity. I suspect this, because it happened hundreds of times over a few days, that I would scroll some document or web page, pause to read, and then trip when trying to scroll again, if I took any time at all to read or otherwise not show activity. It was way less than a minute.

4.0 out of 5 stars Really good product Aug. 26 2013

I like it. The only problem is the incompatibility with Android OS. I think it should be clarified in the description.

I have a PC hooked up to my TV and I use this little guy to control it. The battery lasts forever, it is small and compact so you can store it easily and it works like a dream.

4.0 out of 5 stars Great for HTPC, make sure dongle is visible Aug. 18 2014
Verified Purchase
Good keyboard overall. Used with Windows 8.1, most of the key bindings work, really useful for sound for example.
Mouse is smooth and easy to use. Cool thing, above the ESC key there is another click button, so you can hold both ends of the keyboard and use both thumbs.
Right shift and backspace are quite small, but you'll get used to it. If you need this keyboard it's probably not to write a novel anyway right?
You WILL have to use a USB extension if you don't have the dongle directly in front of you, or reception will be intermittent and very frustrating. Behind the case or in front of the case but at floor level will have bad reception. Once next to the foot stand of the TV it started working perfectly.
Only bad point is the software that is supposed to help you re-map keys. It is a steaming pile of garbage that does not work... I mean not at all! People have been complaining about it for years and it is still completely broken.
You can live without it, so not a really big deal.

TL;DR: Get it if you want to control your PC from your couch, at this price there is no competition and it's good.
