I started out with Pax 3 and I won’t be knocking on it. It’s great portable that fits in your pocket which is very convenient. Taste and battery are okay, especially given the size. The only real downside is cleaning because vapor path goes through the device rather than being isolated into an external stem but that’s the price of portability. But there’s just no comparison on how much oomph you get for the same amount of flower.
I think there are some controversies on build quality and warranty claims with Pax on the latest models (Pax Plus) but that Pax 3 is an indestructible tank so hold on to it :)
TinyMight 2 is being revised quite often so it’s not the same device as couple of years ago. They got rid of glass chamber in favour of a steel one, reworked that dinky button etc. IIRC even the heating element design was updated.
