Worth every penny.
on June 27, 2013
Glass is a tad bit thin and graduations a far too inaccurate for precision measuring but then again expecting tough glass and high precision would be tremendously unrealistic for the price. I was actually pleasantly surprised at what I received. The tops are uniform and square to the bottoms, as well as uniform enough to accept a stopper and seal completely, if needed. Glass is clear (no ripples or runs) and well produced, and the the overall uniformity and consistency from unit to unit is considerably beyond what I expected, for the price. I have not used these for precision measuring or heating anything so I cannot attest to these attributes. Again, I think it would be highly realistic to expect premium durability and material properties for less than what the smallest flask would cost in superior formats. I was very pleased and feel I received more than what I paid for.
While the glass does feel a tad thin, it is clearly more durable than I expected.
I have since dropped the 1000ml and the 250ml flasks from 1m+, both times expecting a huge shatter and glass shrapnel but neither of them broke!
