Solid. Perhaps a bit heavy.
These seem to be quite substantial and may be a bit heavier than most. Note that there is a plastic lip on the top of the glass which could be a problem if you need to heat these much.

Thick, durable and heat resistant.
Thick glass. Not a flat bottom but still allows for use of magnetic stir bars. Anti-drip ring is essential and works well. Fit easily into Insta-pots and pressure cookers. Great product, especially for the price.

Cracks after heating.
I have purchased this product twice for use as a container for yeast starter, and it works fine for that purpose but both times after autoclaving the flask just shatters. The first one broke after pouring warm water into it while it was still hot, which I assumed was my fault so I just bought another. The second one broke after simply letting it air-cool after taking it out of the autoclave. Compared to my genuine borosilicate glass bakeware (pyrex) which can tolerate ice cold water right after heating, this is a joke. I really doubt this is real borosilicate glass.

Quality
I teach science. Quite surprised at the excellent product construction including cap. Worth the cost.

Curved bottom
The bottom is not flat. One flask was quite scuffed, but usable. The cap seems to work...would prefer something with PTFE as a liner

Perfect for hilarious coffee containers
Was looking for something silly to carry my ice coffee and, these were perfect lol! Add some caffeine molecule Stickers for labels, and perfect! These have held up well to repeated washings, and even dropped one in the sink once, no damage

Buen artículo, pésimo empaque.
El producto se ve de buena calidad pero viene en un empaque demasiado sencillo y llegó rota una pieza, además el empaque no tiene ninguna indicación de que es un material frágil.

Buen producto, pero mal envoltura de envío
Buena calidad en el producto, sin embargo, una pieza llegó rota, no trae indicación el paquete que se trata de un producto de cristal.
