My Cera device arrived today. Since TET still has a few back orders to fill they sent me an early model prototype. Its basically the same as a current production model, just used. It has been updated with the new lower resistance switch and it came with an Orbtronic PD 2900 10 amp high drain battery (18650 3.7v 2900 mAh) that is made in Japan. The device is big. The TET website says 1 X 6 and 10.7 oz. Mine measures 1 (25.4mm) in diameter, 6.3 (160mm) long from tip to switch, and weighs 9.5 oz (270g) empty (without the safety pin which I will probably never use). Add the 1.6 oz (46g) battery and it totals 11.1 oz (316g). OK, its really big. This is definitely my kind of device, its solid. Then again all of my backcountry gear is durable stainless steel not lightweight aluminum or high dollar titanium. Speaking of titanium, Im not sure if the titanium Cera is available yet or just how much lighter it is. Time to fire up the atomizer and start breaking it in. Ill be back!
