Indeed, you'd better spend your 'talents' elsewhere.
Your 'talent' of getting everyone angry in your first contacts on this forum is not needed here. I will lock your account for posting for one week and
hopefully you cooled down again after that.

Old topic, but still strong. My experiences from different vendors, having ordered thousands worth of stuff:
Deschem: my favorite, has wide selection and quality has thus far been good (enough for me), some glassware have imperfections like cast drips and
some dried up dirt is not uncommon, but nothing that won't rinse easily off - I wash my stuff anyway before using them for anything critical, and if
you need "essential oil pure" whatever that means, you will rinse them with piranha or aqua regia prior to use. Once when I had trouble due to
shipping reasons, the response was very swift and professional and I'm most happy customer of theirs.
Nanshin: one fritted filter just slit apart when drying, indicating poor annealing. They went silent when I inquired about the matter. Their vacuum
desiccator stopcock also broke off when carefully attaching a vacuum hose, it was brittle to touch. From two experiences their quality might have some
room for improvement.
I've also ordered some small stuff from other vendors, generally having no other issue but sometimes extremely long shipping times.
(Europe) Neubert-Glas offers good quality, but their communication and shipping times can have somewhat wider tolerance.

Fyndium - I have very good experience with nanshinglass. 2 orders from him, both above 200 Eur. I ordered 120 mm long capillary melting point tubes
and he mistakenly sent me 100 mm - after notifying him he sent me immediately 120 mm. Thermometer adapter had a star crack and he sent me new one. He
always apologized and responded very quickly both times.

Yeah ithink the same thing.its just not washed very well and there's no telling whether the factory has its own water recirculation system or what the
quality of Chinese tap water is like.my tap water here is full of calcium.
