Vaporents

I have a B1 injector and I love it. I opted for the injector for the wider variety of glass bowls and more restrictive airflow which is purely a personal preference. It was a 4/29 bundle package.

That being said a ball vape is really just a hot coil heating some glass balls so they heat the air when you pull. There are some variables here based on designs but it's almost like asking which is the best stove to cook on.

If you are looking to get rid of the torch it's a great decision. There's nothing like setting the heat controller to 3 hours loading a bowl and having an on demand cloud factory for the direction of a movie and then some.

I can comment on some of the QaromaShop stuff; I have both the Qaroma and the Taroma 2.0. Contrary to what some have said about ball vapes all being more or less the same, I've found that this is not the case.

Both the head design and housing material affect draw, flavor and effective extraction temperature.
Whether the difference is appreciable to one ent vs. another is purely personal taste. My Qaroma (fused quartz) has very different flavor than the titanium Taroma, at the cost of a significantly higher operating temperature.

In my opinion, though these units cost more than a DIY option, these are a buy-it-for-life item and worth the one time added expense.
