We love this little book light and bought one for each child. They can be clipped to the book because they are really light or you can clip them anywhere on the bedframe around you while reading. I also love that we can put them on at night if the kids need something or just for checking the time, without using bright light which wakes us all up again.
It has 3 settings low (nearly like a night light) mid and strong, which is awesome as you can totally choose what you need.
We read quite a lot but we still only need to charge them less than weekly. And its so easy as I just charge them when I get up and they are full and bright again for using them in the evening.
We absolutely love this product!
