These "products" are sold by many vendors out of china. Problems include the following:
They seem to be sold off of the "factory reject" pile in some cases, failing rapidly after purchase.
There are a number of special purpose versions which are being sold to the unwary as "complete" VFDs. The usual one is "Isacon". but there may be others.
The insides that I have seen varied from what I would class as crummy to downright dangerous. Definitely NOT industrial quality devices in my opinion.
As a result, I am classing these (IMO) POS units as equivalent to the hobby machines that are banned, so they get banned from now on. I will close threads about them unless instructed by the site owner not to, or unless the brand improves.
This goes for the units under other names as well.
This is a Huanyang:
