Your post above really belongs in the TM thread if not that ask FC thread linked btw totally off topic for the Tetra
The original model was Tubo Evic then Tubo Dual, then Tetra heater evolved to be in the Dual, then Tetra P80 released and has seen some slight updates with each drop (the next upcoming one will feature replaceable heater screens) -- Wismec Sinuous P80 it's just the name of the mod the Tetra is connected to, that's why it is called Tetra P80 (Evic was the name of the mod connected to Tubo) and Tetra X is just the heater that can be connected to any mod with a cord. Does that make sense? I'd suggest reading these threads more
Tinymight is my overall favorite as a portable, dry with aftermarket cooling stems and hooks etc, but I use my TP80 more as a water vape at home, they are similar yet different, as you can see in the linked comparison thread above. Yeah so any of these on demand, pure convection, style portable vaporizers will fulfill your needs... (Rogue and 722 are session style devices with hybrid heaters that have a lot of conduction present basically cooking the herbs creating the vapor for you instead of you holding down a button inhaling the hot air through the herbs to create vapor like convection)
Yeah it's a great option, a bit more analog, which is good because you don't want to get stuck up on the digital screen and temp settings as they're going to be different than what you're used to anyway, you need to focus on the device in more of a vacuum to get to know it for you... Not going to be like anything else really. Either way you can always fix the glass, but it requires being sent to manufacture, unless you can possibly do things yourself, but they are pretty durable anyway, and glass stem as your chamber and vapor path means that is always easy to clean and replace...
