Received wrong item
I receivd a pair of work pants. They were probably worth more than than the cost of these flasks, but a 40" waist and 24" long just wont fit me. I returned them and received the correct product, but was credited for a lower priced item that I had ordered at the same time. This item is great, and I'm sure all the headaches I've had with this order are the fault of Amazon, and not not the seller.

Great value.
Used them numerous times at temps above 120c. No issues and they are still in service. They are consistent in size and the necks are ground perfectly. Not as heavy as the Lab boy flasks but for general use they are perfect. If I was going to heat something over 250c to 330c , I’m using heavier glass, no reason to risk a heating mantle. These will probably be just fine , but I don’t want to risk a big mess if they can’t handle extreme temps.

Keep spares on hand for the occasional disaster.
Properly packaged, standard item, on specification.

Examine carefully all new glassware
Two to an order, one flask was cracked at the bottom, most likely due to improper annealing. Otherwise, the intact flask is flawless. This is the first time out of perhaps a hundred pieces of glassware ordered that one has arrived cracked.
