The Twist Slim 2.0 has a sturdier feel that has more weight in your hand, and immediately tells you it’s a quality device. This new model has a more streamlined silhouette. The collar that used to hold the threading at the top of the battery is now flush, making it look longer despite only being 1cm taller than the 1.0 version. The flex temp dial on the bottom has also been updated. We lowered the voltage slightly, with a new range from 2.0V to 4.0V. This hits more of a sweet spot with oil cartridges that are notorious for burnt coils. Each voltage level on the dial is now a notch that clicks into place, so you know exactly how hot the device is heating at any given moment. The Twist Slim Pen features pulse wave technology, or buzzing feedback that tells you when the battery powers on and off, and when the cartridge has made a connection with the device. Click the button 5x to turn on and off and click 2x to activate Prep Mode. We highly recommend running a cycle of Prep Mode every time you turn the Twist Slim on. It does wonders to clear stubborn clogs in the cartridge! This battery has Safe Sesh Mode enabled, which means that the device can only heat in 10-second increments. This prevents overheating, protects the cartridge’s coil, and preserves those tasty terpenes. There are 2 methods of taking a puff; press the button and inhale, or simply inhale! The battery life of the Twist Slim 2.0 is amazing. We gave it automatic shut-off, so it turns itself off after 10 minutes of inactivity. You’ll be amazed at how long you’ll go between charges now! Charging up this device is quick and easy. We include the classic Ooze Smart USB charger that screws onto the battery like a cartridge and uses a wall adapter. We’ve also given the device a type C charging port right next to the battery. Use a type-c charger (sold separately) and the device can be used while it’s charging! There’s no need to let low battery power kill your vibe. Both charging methods rapidly recharge the Twist Slim Pen.
