Where did you get that? There were a small number of units from one of four different manufacturers that had spontaneous firing issues, not catching fire. The one manufacturer was Yung June and it was the version 1.5, zillions of which are still out there and not catching fire. CCV pulled it from his site. Most of the other sites just sold out of them. We don't know what caused it, the extent of the problem or even whether it was isolated to a particular shipment that CCV happened to get. It's a little early for a blanket condemnation or pre-fact hysteria.
If you have any information about any lesser known manufacturers of the version 1 Lavatube who had their units spontaneously firing or causing a fire hazard, please inform me. I've not heard of any. AFAIK, it was one version from one vendor and one manufacturer.
The version 2, made by J. Lin, has had no such issues, nor has the Lambo, the other "knockoff". BTW, when you make significant changes in the circuitry of something and improve it substantially, it hardly qualifies as a "knockoff" when the word is used in the derogatory
sense the way you use it.
When L. Rider starts copying the circuitry of the J. Lin version and calling it the V2, that will be a knockoff.
