Many new users of the electronic cigarette / personal vaporizers (PV's) quickly learn that the importedelectronic cigarettes battery packs, switches and electronics are highly prone to failure within days, if not hours, of purchase. The batteries are woefully undersized and may last an hour or less under heavy vaping. Many electronic cigarettes also lack a manual button that gives the user complete control over the duration of the atomizer heat cycle. Enter the Super-Six Electronic Cigarette. The Super -T1 The Super-Six is a custom-made, electronic cigarette made right here in the USA (excluding consumable parts such as atomizers and batteries) that incorporates many industry firsts and addresses the problems of imported electronic cigarette products. It is available to fit most popular atomizers including the 510, 901 and 801 (a personal favorite here at Super-T and the only adapter that is available with adjustable air draw). The Super-Six utilizes one 14500 protected 3.7 volt battery for 3.7 volt vaping, which is what most all imported electronic cigarettes operate at. -SAFETY NOTICE regarding CR2 Batteries. Though two CR2 3.0 volt batteries will fit inside the Super6 as they are nearly identical in size to the 14500, I cannot recommend using them in your Super6 as it has been reported that they can fail without warning possibly causing injury. Super-Six Features include: - Adjustable air draw. The first of its kind in the industry. Now you can adjust the draw to your liking! Simply turn the integral adjustment screw to adjust! Note: Ajustable draw is only available for use with 801 adapters/atomizers, not available on 510 or 901 adapters/atomizers. - Completely mechanical, no solder, no electronics, improves reliablity. - Three, machined safety vent ports. Another first in the industry to incorporate safety venting into the battery housing. The Super-T1 allows venting away of any battery gases from the user in the unlikely event that a battery should fail. - All-machined aluminum, stainless steel and brass. - Billet-machined button with replaceable, adjustable contact. Extremely reliable. - Knurled front cap for grip and easy battery replacement. - Rear-machined grooves for grip. - Battery chamber sealed from atomizer, preventing e-liquid from leaking into the battery compartment. - Slimmest Dual Voltage electronic cigarette on the market! - Multiple adapters available for the 801, 901 and 510 atomizers. Note: Only the 801 atomizer adapter utilizes the adjustable draw feature.
