Anyone ever heard of this company? A LHS started to get them, they say they are made in Cali. They have a couple circ tubes & regular tubes. Seemed kinda decent. Cost for the the circ was $270. I think it was like 16inches tall, they way it felt it seemed like it was 5mm. I found a couple pics online of just a beaker:
From the pictures you posted, they don't look like anything special. Glass doesn't seem to be very thick and the diffuser doesn't look flame-polished and pretty thin glass.
