Use one with the laptop and the other with my stationery bike because it's readout is not backlit.

The description says, "Dual light output: white and blue White light illuminate keyboard Blue light reduces eye strain"No. That's mostly wrong. Now I'll tell you what it really should say, "Five white lights on the bottom will illuminate your keyboard and five glowing blue holes on the top will shine in your face." They opened holes in the top of the blue plastic so each light produces a blue glow on the top. (Why?) There's no way to cover these blue holes. Well actually there is a way to cover them - with black plastic tape. Yes, that's right. They made this light with white lights shining on one side and holes in the top so a blue glow can shine out the top. (Ridiculous.) You could turn the light unit over so the blue light shines on the keyboard but this will also cause the white lights to shine on your face. (absurd!) OK - on the positive side - this light unit plugs into a USB socket and lights the computer keyboard as it is supposed to. And it will do that even better after you place black plastic tape (electricians tape) over the blue spots on the top. (And I would love to ask the manufacturers this technical question - Why do you call it a "wireless" light? There are wires inside the goose neck, running from the plug to the light.)

Light worked out of the box for about an hour total, then when removed from USB port and reinserted, light did not come on at all. Tried everything, including reboot. Other devices functioned fine in the port, so I know it still had power. Will be returning this one.Also agree with other reviews that the light output was pretty good, but the flex arm was much shorter than I expected, and it did not hold the light position well at all.

This light works great. I work on items for a web store on my laptop during the night and day. Whenever. This light lets me see my keys. The little dash, the underscore, the tilda, etc. without a mistype. My USB ports are all forward on the left and the right. This light focuses on my keys without beaming back in my eyes. It has nice blue lights on top. The two different levels of light are great, but not that much different. The switch on the end is a push button that works great. It stays in the USB port snugly and bends to wherever I want it to be. I compared the reviews on the different lights and ended up choosing this one, and I am glad I did. 100% happy. Love using it during the day as well. Everyone that sees it, wants one. Great to work at night with no other lights on in the room. Kicking back with my screen getting stuff done while everyone else sleeps and I can't. I should have bought this years ago!

If you are getting this to for the reasons specified you'll be one happy person. This thing works amazing.. 5 led's is the perfect number. Bright enough that you can see everything within 2 feet of the light, but dim enough that your not going to keep anyone else in the room awake. I was worried that this would be cheaply made and break, but upon receiving it I realized this thing was built beautifully, with a long enough cord that you can angle it high enough to not have your hands hitting it while typing. This was defiantly designed by someone who actually needed one! haha.Over all I cant find one thing I don't like about it accept for the fact that I only got 1 (should have got a bunch to give out as presents) because the shipping was 30 cents less than the actual unit =x

I work as a freelance computer programmer from a powerful laptop computer, and I sit in chairs or on the floor, never at a desk, in all sorts of lighting conditions, including darkness when other people are sleeping nearby. I usually have the computer on my lap at an angle, so I have to crane my neck to see the keyboard straight-on. My newest laptop has no keyboard light. I researched the various USB keyboard lights and in the end I purchased two of them - this one, and the "Portable USB LED Flexible Work Light for Laptops/Notebooks" (http://www.amazon.com/Portable-Flexible-Light-Laptops-Notebooks/dp/B002WI8GG8), which is rated higher. I am in an excellent position to give a detailed comparison of these two lights.I can now report that in comparing the two, the one here is clearly superior to the "Flexible Work Light", so I'd like to push its rating up in comparison with the other light I'm comparing it to.Both lights have switches, and both switches are convenient to use in their own way.It is true, as other reviews pointed out, that the gooseneck of the "Flexible Work Light" is longer by about 4 inches or so than this light. However, neither light is even close to being long enough to be able to arc over the top of the keyboard and shine down directly from above, rather than from the side (for MY laptop computer, which is gigantic), so the extra few inches of the "Flexible Work Light" makes no difference for me. For those with a Netbook or otherwise very small laptop, the extra few inches might make a difference, I suppose.Because neither light is long enough to reach over the top, I have two lights - one on each side of the computer. (That is how I am able to compare them so carefully - they are both in place and turned on right now, with the current light on the right side, and the "Flexible Work Light" on the left side.)The gooseneck cables themselves are slightly different, but of equally solid quality in both cases. If anything, the gooseneck of the current light is slightly thicker and stiffer - but they're both solid.The USB connection is identical for both, and both remain in place just fine.Another reviewer reported that the connection between the gooseneck and the light for the current light was weak. I do not see this problem at all. Both this light, and the "Flexible Work Light", have a very solid connection between the gooseneck and the light mechanism, and evince no indication that this connection is problematic in any way.The main reason that this light is significantly superior to the "Flexible Work Light" is that it is MUCH brighter. As noted, I use them both at the same time, one on the left and one on the right. The "flexible work light" seems like it's probably about what you might expect for a USB light, and if I didn't have the current light being reviewed to compare it with, I would resign myself to the fact that even with a typical USB light, the keyboard is still dim enough that I have to crane my neck sometimes - albeit much less than the amount I have to crane my neck and squint with no keyboard light at all. Still, instead of feeling good about the USB light and feeling that I can work in dim lighting conditions in a completely relaxed fashion, I would still feel frustrated about having to crane my neck and stare at the keyboard a bit, even with the "Flexible Work Light". I think it's no exaggeration to say that the current light being reviewed is 8 or so times brighter than the "flexible work light", and in addition, it is diluted a bit better as well. No neck-craning is necessary at all when using this light, and there is not the slightest hassle in immediately seeing the keys clearly when you glance at the keyboard from any angle.I still need to have two lights - one on the left and one on the right - even with the current light being reviewed - because it shines from the side and illuminates one side of the keyboard much more brightly than the other side. And, on a related note, even though it's a bright light, the light is still localized so it won't bother others nearby in the darkness unless they are sensitive to any light or unless the light faces in the direction of their eyes. (The "flexible work light" might bother them as well, but not as much.) It is true that if the light is angled in such a way as to face directly into the eyes of someone nearby, the glare from the lightbulbs of the current light I'm reviewing is much worse than the lightbulbs of the "flexible work light" when you stare at the bulbs straight-on, even though the light from the current device I'm reviewing is diluted a bit better in terms of how the light shines down onto the keyboard.Also - and this is important and I almost forgot to mention - the current light being reviewed has two brightness settings (the "flexible work light" does not). Even on the lower setting, it is still 5 times as bright (or so) as the "flexible work light", but there are occasions when the light *is* too bright for me on the high setting (when it's completely dark in the room), and in these situations the lower setting is just fine. (Even at the lower setting, the glare of the bulbs when you stare straight on is much worse than the "flexible work light" if you stare at the bulbs straight on.)I should also note that when it is *completely* dark, the "flexible work light" actually works well enough (though it's still not as good as this current one I'm reviewing). It's only in situations of "medium" light, or "grey" surroundings, areas with deep shadow, etc., in which the need for a BRIGHTER light is most noticeable. In these "grey" settings, you still need to crane your neck to see the keyboard, almost as though it's totally dark, and the "flexible work light" comes close to being useless in these situations. The current light I'm reviewing, however, is absolutely sufficient and is perfectly bright enough when it's on the high setting.I am currently on the site to purchase a second one of these, to replace the "flexible work light" which is currently on the left side of my computer. So I thought I'd take the opportunity to review this and give it "5 stars".
