Works well, good for desk work when you are just sitting and not writing.

Not quite low to the ground enough that my knees don't hit the bottom of the desk. We sawed off the front moulding of the desk, but it still works better if you just use it while you're thinking or reading rather than intently writing.  I am short, and I can't imagine how a tall person would use it under a keyboard-height desk.  It works well, but the display does not really give an accurate measure of miles, but really, the deskwork is the goal not the exercise achievement!

Useful. I keep this on my desk at work and it's small enough not to be noticeable or a distraction on a daily basis. It's also not too loud for an office environment. I like the simple power switch - I just reach over to turn it on/off as needed and can even tilt it up/down.

Works pretty well for large keyboards. Ergonomically one shouldn't really be resting one's wrists while typing but between bursts it does feel nice. Does not seem to want to last long  the fabric top is already starting to fray at the edges. But pretty good value anyways.

I always need pens at work.  I prefer retractable ones as I loose the caps of the other ones (and you can always click them to annoy folks when a meeting runs too long--just kidding).  I found these pens to write smoothly, they require very little warming up (squiggle on a scrap piece of paper till the ink starts flowing).  The clear barrel gives you an idea that you still have ink in the pen (I have had a pen run out of ink in the past in the middle of a meeting that I was running--major embarrassment begging for a pen!).

These do have a fairly wide ink path.  It is not a fine line.  I think these are some of the wider ink pens I have used.  I write fairly large, so it's not really a problem.  If you write tiny though it could become an issue.  They are comfortable to hold, and at this price, I can stash them in different notebooks or even loose a few and it's no big deal.

I use this often in bed, or on the couch so I can do work and sit comfortably. The cushion underneath is easy on my legs, though sometimes the slope is a bit much. I also find the surface to be very slick! My laptop case has lost the sticky "dots" underneath, so there's no grip to keep my computer in place. Also, my mouse sometimes rolls downward while I'm typing! These are minor though, and as long as I'm paying attention it's manageable. The color is like a robin's egg blue or a tiffany blue, with a gray/black cushion bottom.

I have only good things to say about this product. I use it mostly write/work on my laptop while sitting on the couch and it is perfect for this use. It is also good for eating while on the couch.

Pros:
1. The table is on rollers and is easy to move around
2. The legs of the table can be slid under the couch so the tabletop can extend over the couch. This allows me to sit back comfortably and work without having to lean forward.
3. The height can be adjusted by a knob. This also maximizes comfort while Im working so I don't have to lean and strain my back

I bought one of those seated bicycle things for under my desk and immediately learned that this was going to be useless because my knees kept bumping up under my desk as I worked.  Uncomfortable and annoying.  However, this system does work well keeping my knees pretty level, so that problem is avoided.  It's not terribly easy to swing your legs side to side because a) my desk has drawers on either side that impede sideways movement, and b) it takes more coordination and thought that I can offer while I am working.  However, swinging my legs back and forth is smooth and easy, relaxing and fun.  You're not likely to break any sort of sweat on this thing, but it's more movement than I am currently getting when I spend all day at a desk, so I'll take it!

This works well for my purposes. I like that it has a scroll wheel that's fairly convenient to use, and otherwise works the way you expect it to. The removeable wrist rest is nice. I've used it with and without.

Now, for the short-comings: I've gotten used to my Logitech trackball, so a larger ball would be good, as would metal points for it to roll against to make it smoother. It's not bad now, but could be a bit better. But mostly, I miss the thin overbuttons that let me click backwards or forwards through the browser.

Some reviewers talk about the button placement, and while it takes a bit to get used to them after using my Logitech, it's not bad, and they work fine.

That's it. It works fine at a reasonable cost and is nice with the scroll ring. Just wish it had the imrpovements listed above.

I use this with my laptop while I use my Dragon program for writing.  It was bought to replace the one that came with my Dragon program that finally fell apart.  I use this a lot as I have arthritis  in my hands and it is hard for me to write with a pen or pencil.

I bought this to compliment my Panasonic Toughbook 19 (Dual-touch, touchscreen and Wacom Penabled digitizer) because I needed something with more substance to write with since the factory one is too small for extended use.

I use it to write notes with Microsoft OneNote. It writes, it right clicks, and it erases. It's like writing with a regular Bic pen. Hand cramps up after a while. If you want something more comfortable, look for a different one, but this one is Great Value for the price, and it works. Can't go wrong for less than 30 bucks. It's the cheapest one that I could find.

A nice feature would be something to attach/clip it to the laptop, like one of those small holes to string something through like that of a flash drive.

Recommended!

These are great as a small-footprint desk fan at work.  It doesn't move a ton of air, but it's just enough for when the AC at work isn't working as well.  These are also pretty decent for white noise for sleeping.

Actually works pretty well though it takes some getting used to, also picks up everything so put it away from your desk because you'll hear the shuffling of your papers and such.

Works great for a desk or few feet away...any farther away  and this is not fan for you. So far so good.

Good if you use it on a desk as advertised.  Not that good for lap use since your trackpad won't "click".

I hate the idea of sitting on my rump at the computer, but since my job requires it for several hours per day, I picked up this little beauty to keep under the desk so I can pedal while working. The grips on the feet do not work so well on tile or hardwood floors and DO slide, but a couple minor modifications made to the feet prevent this. (aka I used a caulking gun to apply silicone around the feet, let it dry and that prevents it from sliding).

I have a very flat reading desk--I put the product on that desk and use it as an area for note taking and doodling--works great.  I write words from may reading that I must look up.  In general, I find it great fun.

Great for resistive and capacitive screen; not super since it is more like a brush than a pen, but it helps when you are on the go and wants to draw something quick.

I can't really write with it comfortably, but it serve the purpose.
