The Kandypens K-Vape Pro is simple to use, plus its small and lightweight size makes it an easy carry. It's a great entry level vape with a nice 0.5-gram ceramic heating chamber and 4 temperature presets maxing out at 428F. The battery is 1100 mAh strong and allows use while charging! What sets the Kandypens K-Vape Pro apart is its comfortable glass mouthpiece with “cooling technology.” This mouthpiece is integral to the experience of the vapor path. It incorporates a clever design that helps disperse the hot vapor into a more comfortable and flavorful hit, even at higher temps. Kandypens thought ahead and included two mouthpieces in each box!
