First of all, buying the electronic cigarette from this company is a bad idea. They are nothing but liars and give you the runaround so you will never get your money back. My husband got sick from the electronic cigarette that Greensmoke sells. He got a reaction in his throat from the ingredient that's found in antifreeze that's in the vapor of the cigarette. He spent $185 on the product and can't even return it. Their customer service department is great if you want to order but when it comes time to return anything, forget it, you are fresh out of luck so please do not buy from greensmoke.com. read full review »
