Even after long sessions, this vaporizer stays cool to the touch so you don't need to worry about burning yourself packing another bowl. We love it, it's great for when we have some friends over and also works to freshen up the air in our small house. HIghly recommended.
Arizer says the V-Tower will pay for itself based on the herb it conserves and I gotta say, so far I believe them. I rarely have to refill the bowl.
When we're not taking big rips, we love using this vaporizer to heat essential oils and fill the room with an incredible aroma. This is a great buy.
