For a month I found these quite useful. Not bad to have a set of readers readable available. However, yesterday, they simply popped out of the case broken at the bridge. Not clear why probably just because they are poorly made and the tension took a toll. Still a high price to pay for one month's use. It would also be great if 1.00 or 1.25 strengths were available As a back-up with minimal use, these might hold up, I have a pretty light touch, so most may break a little earlier.  UPDATE: The seller was very quick to offer a replacement. I would have just deleted the review, but since others have experienced the same problem, I think it is still fair to warn others of possible unexpected breakage. That said, I have not had any problems with wearing them when occasionally needed. It make it so much easier to not have to carry a pair of full eyeglasses around. I recommend this with reservations.
