I have 2 of the Apollo VTube Mini's and they work great. I don't need anything over 2.5 amps as I like to vape - not weld. Vendors aren't doing any of us any favors by not specifying exactly what they are selling - can anyone say "misleading"?
The problem isn't the manufacturers, it's the vendors and us. Why call something built by a different company a version 1.5 or 2 or 3? It's a version 1 from that manufacturer. It may have a higher amp limit or some other feature, but it's not a higher version of anything. Its the 3.2 amp verson, or the 4 amp version, or the Lambo 2.5 amp version of whatever they choose to call it. Unless you can show me previous versions of the same thing by the same manufacturer, it's version 1.
