Summary: My goal is to point out some of the problems I've had with this light and also suggest what I think is a grat alternative. I've tried to use this light a couple times and was never happy with it. The light didn't stay in position, seemed to occasionally get in the way of my hands, and frequently blocked my view of the screen. Nothing was a showstopper but I wanted to get rid of the annoyances if possible.
Summary: We were really disappointed in this product. The idea is great and, initially, it did a great job of lighting the keyboard. After about 3 or 4 days, the lights started to flash and burn out. We now have three lights that don't function at all and 2 that flicker all the time. Did we get a defective light or is the craftsmanship poor?
Summary: This unit is not very bright. Would not buy again. It would be ok if you just wanted to illuminate your keyboard, but not for reading (get an illuminated keyboard instead if this is what you're after).
Summary: Just purchased a new laptop and cannot see the keys in the dark. Purchased the Kensington Notebook Light based on other reviews. However, the light is too direct. Needs to be more of a flood light to cover the key board. I don't like the fact that all the stress is on the port.
Summary: Great in theory. I'm surprised at all the positive reviews, though. (I suspect many of them are Kensington plants.) Unlike what others have said, I find the arm strong enough, but I agree that the light is weak, even on the higher setting. It doesn't illuminate much of the keyboard, but I mostly touch-type, so it's not that big a deal. Most frustrating, however, is the glare.
Summary: The neck is too weak - does not adequately support the light in useful positions, where it would actually illuminate most of keyboard. It is MUCH OVERPRICED here! It is about 20% less at one retail chain, but even that is too much money for product of this quality. I will keep it, but I will have to use something to fashion a tiny "lampshade" -- otherwise it keeps shining annoyingly in my eyes or reflect off the screen.
Summary: I purchased this device so I can enjoy the keyboard lighting that my work Lenovo has built in yet lacking on my personal HP laptop. It's certainly bright enough, but the beam is so narrow it simply makes a bright spot in the middle of the keyboard. Take a lesson from laptop vendors who make built in keyboard lights; one lamp in the right spot is perfect. It simply needs to add a diffused lighting to the keyboard.
Summary: I like the fact that this notebook light is light in weight, very flexible and convenient. But I had expected much more illumination than I got. It does help to see the keyboard when typing in dark, but that is all...nothing more.
Summary: Why do I get the feeling that some of these later reviews were written by Kensington people? The fact is, this light has some unique features that most USB lights don't, including an On/Off switch and two brightness levels. However, that doesn't come close to overcoming the drawbacks. First of all, the price is way too high for what you are getting. Also, the brightness difference between four and eight LEDs is negligible.
