I had a pair of the Wisteria glasses for over 3 years. Lots of compliments and well....I could see better. The neck hanging glasses seem to last a lot longer because as I took them off I naturally hung them at my neck. I always knew where they were. I often wore out an 'arm' on regular glasses because when I took them off I folded one 'arm' in to hang them off my pocket or worse....put them down 'somewhere'. I was at an event where I had to wear a name tag around my neck and the glasses must have gotten knocked off by the strap holding the name tag. I couldn't find them. Wisteria wasn't available for the longest time. Finally, able to replace them. Woo hoo!!!
