Watch glasses
I use these daily. One larger one came chipped on the edge a little, but I use it anyway. They could be packed with slightly thicker foam between glasses. There were a couple of large glasses in the set anyway, so I'm not worried. The glasses are concave/convex a good amount, so liquids drip back down in the center of the beaker when heating solutions.

Nice watch glass beaker covers.
Work very well.Edges feel good and not sharp like my older covers.

Just broke, wasn’t even boiling.
First one I used was the smallest. About 10 minutes in on low heat (2 out of 5) it just split. Hopefully just a random poor one, air bubbles in glass? I will be looking for a different brand & returning.

One glass broken
The glasses seem fine but one of large ones was completely broken. I don't want to take the time to return it. It's just kind of disappointing.

Basic but thin
I wish the glass was a bit thicker/sturdy. They break easily

They are what I expected.
I havent used them yet, but they appear to be exactly as advertised. They are likely tempered soda glass - fine for the intended/described use. They should NOT be directly heated - not used as container to hold something to be heated - not exposed to flame - not borosilicate. If this is news to you, you probably should not do what you're planning.
