I own three of these! The battery life is incredible! Once charged, which takes less then 1/2 hour, the battery will last me for a month on med. light. The high beam drains the battery pretty fast, but medium level is a perfect tone for reading at night.The light works well but unfortunately when I had to recharge the battery, I was no longer able to get the 9 brightnesses to work. The only lights that work are the 3 light settings for the yellow light, no LED lights working. What am I doing wrong???I have used this rechargeable light for over a year and still am very happy with the brightness and how quickly it recharges. I also use it when I need a hands free spotlight such as when doing my nails or reading fine print on an ingredient label. The flat base and strong clip make it very useful in a variety of situations.Love this book light. It is brighter than the previous light I had by Mighty Brite. This one has a nice yellow light that's good for reading. Fast shipping. Very happy with this sellerThis light is pretty great but not the best. You can see the light slowly dim over time because it's running out of battery. And the bendy neck does not stay in place very well. It's also annoying to feel the clip underneath your page.I use this for reading, drawing, and even knitting! I wanted something that wouldn't bother my fiance when we're in bed. TastsI bought this specifically to light up my amp on stage. Works perfectly! Highly recommend.This works well and the adjustable neck is very efficient. The three light settings come in handy as well. You get what you pay for, so as long as you don’t expect something from Sharper Image you will be good
