Pros: Its thin, It was pretty cheap, it has an extra usb port, mine required no drivers to work even including a lot of the extra function buttons for music playback , I loved the trackball it is actually really useful and best of all you dont HAVE to use it because of the extra usb port.

Cons: The only two problems I have with this keyboard is the enter key/key layout, the enter key i almost always have to look at in order to hit it it seems much smaller than on other keyboards and unlike many kayboards the enter key is vertically aligned instead of horizontal, as far as the other keys go you better be ready to look at the 'board cause some of the keys are in weird places. My other pet peeve is the tendancy to cater to windows media player so most of my extra function buttons work including the browser ones with firefox but some of the media player buttons didn't work however I am pleased to report that the media player button opened winamp which is my default but the track skip buttons didn't work.

Overall Review: Overall i like it quite a bit barring those few things which I mentioned its actually very nice and with the 6 foot usb cord extention I bought to go with is I can sit on the other side of my room and fiddle with things like changing songs.

Pros: I bought this for my second desktop computer I use for music and downloads. I needed something I could quickly grab and use in my lap, therefore a mouse wouldn't work for me. The track ball is optical so there is no problem moving the cursor around. The click buttons are conveniently located for the left hand. The key strokes are above average too. The product comes in the retail box.

Cons: I don't see how someone could use this for gaming. I regular mouse would slaughter them.

Overall Review: I didn't buy this for gaming so I am very pleased.

Pros: Overall it's a nice key board with good features and a nice layout it's smaller than expected which was actually a huge bonus.

Cons: Scroll wheel and extra function keys stopped working after just two weeks of use. The scroll wheel feels loose like it broke off of it's mount. It's just wobbling around and is stuck.

Overall Review: I like this key board but I probably wouldn't buy it again. It broke way too fast for my taste. I would wait until these guys figures out how to make a more durable product.

Pros: It's nice, it's light, it's the perfect size. Track ball works well even though it's a bit rough. Nice layout and smaller than I expected which was great for my media pc. It's well made and nice looking

Cons: Linux and over all product support is terrible. The basic keyboard works and was detected out of the box by ubuntu, but none of the function keys work unless they're short cuts to default key combinations like cut and paste. There's nothing anywhere on their website about this keyboard even for windows users. Seriously, just go to their website and try to find drivers for this keyboard. Their web imterface is in engrish and there isn't any info any where about using this in linux on the web.

Overall Review: Overall i like this keyboard, but seriously it'd take one person just one or two days to add this to key touch for linux support and the driver could just be there for future additions. it really is a nice key board and i would have given them five eggs easy if they'd just get their act together and add support for 14% of the OS market.

Pros: Low cost by a factor of 2, wheel feels nice and doesn't cause me to contort my hand, since the buttons are on the other side. Feels as solid as it should for this price.

Cons: Keys are a little stiff compared to most keyboards, but I quickly got used to that. Some keys are a little scrunched but it took about 10 minutes to get used to that too.

Overall Review: Hey, guy who says the scrolly wheel doesn't double as a third mouse button, PUSH HARDER! :) Seriously, though, it IS a 3rd mouse button. Pass it along!

Pros: I wanted a USB wired keyboard with a built-in trackball to use for my laptop, and narrowed it down to this out of about ten other contenders. It serves nicely for that purpose, and is relatively inexpensive. The trackball responds very well. The extra USB port is a nice touch. If my replacement lasts longer than the first one, I would say that this is a good bargain. But on that note...

Cons: The scroll wheel broke after about 2-3 weeks of normal use, resulting in my first RMA. I think the plastic axle just snapped off internally. The alt/meta/hyper, page up/down, and punctuation keys are all about half-width. This makes touch typing with these impossible for me. These keys really feel as if they were just crammed in wherever they would fit, as they probably were. Also, there's only one 'meta' (windows-symbol) key, and on the left side. An additional one on the right would be very desirable.

Overall Review: I think they could have slid the extra (useless) media keys by the scroll wheel down half and allowed for full-size 'real' keys. Who needs special keys for cut/copy/paste??? Two comments about the media & custom keys: 1. I didn't expect that they would, but none of them work with Ubuntu. However most of them don't work with Os X, either --only the volume up/down/mute keys do. 2. They, as well as the right/left click keys, feel cheap. This is a budget keyboard and that's to be expected though, so I don't think that counts as a con.

Pros: I work with Mobile Data Collections Units which is basically a touch screen computer without a keyboard in our trucks (even the on screen keyboard has been removed). The only connection available is one USB port and I had to use a hub, keyboard, mouse, flash drive. This key board has ALL the functions of a mouse and keyboard plus the extra USB port to plug in a Flash Drive. Plus buttons for cut, copy and paste which also saved me time. The lay out is setup so you can hold the board in your hands and use the mouse (trackball features). The buttons are in the upper left corner to be used with your left thumb and the trackball is in the upper right corner to be used with your right thumb. Worked perfect. My daughter also uses it with our laptop for playing her games.

Cons: None

Overall Review: This board should not really be considered a replacement for a regular desktop keyboard. Some of the keys are a little smaller in size and if you plan on doing a bunch of typing it may take a little time to get used to the layout. However for certain applications this board fits perfect.

Pros: Plugs and plays, works well. Feel is similar to a good laptop keyboard, maybe a little better. Lightweight and reasonably rugged. Survived several months of sofa use and droppage until the dog chewed the wire off of it.

Cons: Cons are minor. 3 ft cord is too short, I added a USB extension. Compact layout takes a little getting used to. Trackball drifts occasionally (a common failing of optical pointing devices) which can be annoying with video players that show controls when the mouse moves ... nudging it stops it, but why doesn't anyone make a k/b with a laser trackball?

Overall Review: I'll be buying another one if I can't manage to repair the first one. I wouldn't have to fix it if it had a USB B port instead of hardwired-in cable.
