I have difficulty getting it to stay on my ear, but the light is bright, and doesn't bother my eyes. The tip is slightly adjustable. It appears to be well made and works great, where I look it shines light right where I need it.
Had Batteries in it but they did not work. Would cost me more to send it back than to buy new batteries, so it wound up costing me $10.00 for new batteries. It does not work as well as I had hoped. Was disappointed.
I bought two over the ear book lights. One works still and one broke within minutes of having it. The light won't stay on at all. The one that works is nice. Hopefully most of them are that higher quality.
