I have both the T1 and the Evo, and thus far I really prefer the T1. The battery life is worse, I am able to get only 4 to 5 drags on each set of batteries, but it gets nice and hot on the 3rd drag and can give some awesome clouds. I am still using the original set of three I received with my initial order, and they seem to be holding their charge just fine, I have not noticed any reduction in output.
I have to admit my Evo has been sitting for a while, for some reason I cannot embrace it as I have the T1. I still get great clouds from the Evo, but I just can't love the packing sequence on it. I did take it to the theater to see The Avengers a couple of weeks ago, along with my vapor cig, and received no nasty looks or comments. It was quite nice getting to vape while 3Ding out.
My T1 is still my everyday pocket vape, it is built tough as hell (dropped it in a lake playing frisbee golf, has hit concrete several times), is discreet and medicates me perfectly. I hate to hear about unhappy users, my experience with the product and the company has been stellar, they even sent me o-rings for my Evo without a request.
I am sorry you feel you wasted you money on your T1 futuretvowner, I feel the same about several I have purchased the last few years, but they all were a learning experience, and as we learn we should make better decisions about our purchases. Good luck in your quest for the perfect vape, I am still yet to find mine.
