I purchased this from a local bookstore well over 3 years ago and it's still going strong. I would have given 5 stars but I travel internationally with it from time to time and am limited w/ space. It is a lot larger than most booklights and that can make it a bit cumbersome to use at times. The pros: great light, lasts long on batteries, have the option of using 2 or 4 AA batteries, sturdy. I would definitely purchase again.Get more detail about ZELCO 12021B Little Totable Book Light.
