The frame of my glasses separated near the nose bridge and I thought they were done. My optometrist couldn't help since that model wasn't made any longer. They referred me to Pro-Mec. Okay, so, if they can be fixed at all, I'll drop them off and pick them up in a week or so. What a surprise when the Pro-Mec people said I could have them back that very afternoon! And, when I picked them up, I couldn't even see where the repair was! That was a couple of months ago and the glasses are still intact. My wife's fashion sunglasses broke at the temple hinge a week ago and we took them in and, again, a perfect repair. These were both $400 pairs so replacing them would have been a hardship. Fixing glasses is a small thing, I suppose, but this was a great relief to find such craftsmen.\r
It's great to see people who do such great work.
Cons: Can't think of any.
