I don't like digital on whip vapes. I think it's bad news waiting to happen, even on the $500 models. You just don't need it and it makes a breakdown much more likely vs. a simple analog vape. At least the Easy Vape has a 5 year warranty. OTOH you can't contact the maker of Easy Vape. That always makes me uneasy. Is it made in the US? China? Will they stay in business for 5 years? And I hate that typical downward whip angle. Of course you can turn it on its side or even upside down, but then the display is hard to read.

The Hotbox is a proven design. It heats up to vaping range and stays there, so you don't have to worry about a temp control going bad. I'd stick with that choice.
