The Viper by Vaporbrothers is amazing. Leave it up to those guys to invent an all glass air flow. The Viper is sleek, compatible, user friendly and you're herbs never tasted so good. NO more gunky or kinky hoses for those of you using the hands free whip. Since it's all glass airway makes for easy clean up. Just soak then rinse. I love this new product and have fallen in love with the box all over again. Thanks again Rachael. Best wishes and happy vaping!
