Good purchase

The glasses of decent quality. I would not say great by any means but it does the trick. Their measurements are a little off though. They are almost 12 mm outside diameter however they're only 1.5 mm thick. I measured several times so that was a little disappointing. It seems to heat up unevenly for whatever reason because any kind of bubble or anything I put into it comes out wavy. It's not that big of a deal but it's not something I'm happy with either. It does seem to be relatively strong however. I have dropped a few pieces onto my floor and haven't had any broken ones yet. For the price I would recommend them however if you're looking for a very high quality glass I would not go with these, I would try to find Pyrex or something similar.
