This is an excellent starter kit for anyone just starting to get into concentrates, while still pleasing the seasoned cannabis consuming veteran. \n Ooze has been in the vaping business since 2015, and the company has extensive knowledge and expertise has continually developed better-burning and longer-lasting vape pens. They are always hard at work on product development, inventing and reinventing, and this latest version of the Slim Twist Pro may be one of their best yet. \n The Slim Twist Pro kit is compatible with all 510 thread cartridges, and you can use pre-filled carts or fill one with your own concentrate oil. Use the wax atomizer to dab your other concentrates with the dual quartz coils. Voltage settings range from 3.3V (recommended for most oil cartridges) up to 4.8V. \n Uses: This pen can be used for vaporizing both cartridges and other concentrates. To use, you activate the preheat mode with two clicks of the button for 15 seconds of continuous heating, which works best with the wax atomizer.

It has a sleek and compact design and delivers a great user experience regardless of whether I used it for a cartridge or another concentrate with the atomizer. I could taste the concentrate while also being discreet and found the product to work very well overall.
