I have owned two pairs of these readers and they are more than adequate to my needs. I replaced the batteries, which was a bit of a challenge, only due to the tight tolerance of the metal to the plastic ( trying not to ruin the grooves in the frame). The brightness of the light makes them not only good as readers, but for close work also. The only downside is the paint on the covers (both the black and brown pair) flakes off. This is cosmetic and in no way interferes with the function of the glasses. I wish I could find a tinted, computer friendly pair. I plan on buying more pairs if my eyesight changes.... Wouldn't mind a stainless steel pair....
