I've had these readers for several months and have been happy with them UNTIL I NOTICED MAJOR LENS SCRATCHING. This scratching is apparently caused from sliding the readers in and out of the case, since I have been very careful with them otherwise.<br />The case is one of the features that makes the readers such a great product. So they are going to have to fix the scratching by lining the case or hardening the lenses.<br />Would love to recommend this product, but not until they fix this problem.
