The Square is a great vape. I have the Phase 1 model, and while it can be a tad finicky, overall it is a great vape. Hits hard, amazon flavor on the earlier hits, and super smooth, cool vapor. The flavor gets pretty bad when it dies off, battery life isn't great, and not very efficient with the large bowls. To compensate I just take a few hits then save the rest for later. It's not the fastest heatup of my on demand vapes, but once it gets going the heatup is just about instant.
