I was hoping for extra lighting to help illuminate darker yarns while knitting but the light in this is too harsh and I could see the stitches better without it. I like the portability, size and ability to clip it on to something but it will probably not get much, if any, use.
The new design of the book light is much better than previous editions. It's flat base/clip make it less cumbersome and easier to keep in place usually mine is on the seatbelt strap as my hubby drives and the flexible arm doesn't feel like it will break. I also love the new switch, slider rather than press. I can't tell you how many times my previous light would be illuminating the bottom of my knitting bag due to being jostled. I bought one for my daughter and one for myself. Love them!
