      Cold fire core

      "Amazing product love the low temp solid build and function would definitely recommend this for anyone looking for the best battery to use."

      Derek C. (5/5)

      The Best, Awesome

      "Fantastic, the low voltage settings give unbelievable flavor even at 3-4% terp levels. Great vessel quality and beautiful coldfire design, what else can you ask for. Grab it while it's around, nothing comparable on the market!"

      Mike (5/5)

      It’ll make you cooler

      "The Coldfire battery is a big time upgrade over the cheap pen style batteries you used to use. It shuts off automatically after a few minutes, so you may find yourself frequently having to turn it back on- but this is a battery saving feature, so be happy! Looks great and feels like a quality product. Nice weight."

      Carter N. (4/5)

      Love the design

      "The cold fire collab is cute. I love colorful vapes because they’re harder to lose if they stand out. I like that this new version alerts you if something is off with the cart. I also like the core more than the other product lines because it’s impossible for defective carts to get stuck in the device."

      jodi w. (5/5)

      Flavorful. Clouds. Wonderful Device.

      "One of the best batteries to hit the market. The lower temperatures on the battery are the best for any cartridge! You can avoid burnt carts with this battery! Worth it."

      Geoff V. (5/5)

      Smooth and Clean

      "I love the addition of the preheat feature. I've previously used the craftsman series and this is way better. It's smoother to pull, the preheat has made easy no cough pulls possible. The grip is very soft and comfortable while offering grip. The button is easier to press and fits nicer into the body. The design is also really cool. It doesn't offer a metal outer shield for the cartridge but I like that. The main downside is that it uses a USB-C and is not compatible with the magnetic cable or base charger. Overall, solid product and my favorite thus far."

      Chris S. (5/5)

      Second Drawer

      "More of a collection piece, Should have been the vessel campus rise then it would have been top drawer"

      Gabriela F. (5/5)

      Cool

      "This is a gorgeous edition to my collection Special times for this special one"

      John A. (5/5)

      Love it

      "The design is sick, and not sure if it’s a smart technology design but turning off after a while is actually amazing"
