LOL, DH got me some similar, only tips are lit. They were fun, but the LCD light is SO bright that anyone sitting adjacent to you feels like they are going blind. LOL.
If you can't knit in the dark as I can, then the lights can definitely help you see what you're doing, but it's rather distracting to everyone else.
Might make good tool for ushers at a movie theatre :teehee:
Additionally, the batteries it takes makes the sticks a little heavier, there were 3 or 4 watch batteries for each stick of mine, and that was for just lighting up the tip. :teehee:
