Before I start, know that I'm a dyed in the wool MTL vaper, who only uses AIOs and doesn't care much about flavour. I love simplicity in my vaping. I bought my Joyetech eGo ONE TFTA from Fasttech for about $30 all up. It's genuine - I checked. The TFTA stands for "top-filling top-airflow", and it comes with 2 x ProCL 0.6ohm coils. Other features include AFC (air flow control), the battery capacity is 2300mAh and the tank is 2ml. The blurry picture below shows the TFTA on the left with a basic eGo ONE and a Suorin AIR kit. The TFTA doesn't come with a drip tip, which I found rather surprising, but the 'mouthpiece' allows you to insert a 510 drip tip, which I've done (as shown). As you can see, the TFTA is significantly longer, wider (D22) and heavier than the eGo ONE, but still conveniently sits in my top shirt pocket, with just the tip showing. Filling is much easier, through a hole in the top. I was pleasantly surprised to find that I could use it with the supplied 0.6Ω coil without it spitting and gurgling. The AFC isn't as tight as I like but it's OK. (I think that the manufacturers have gone away from tight AFCs because they have the potential to burn out coils too easily.) I used the TFTA in periods of several hours over a number of days, and found it quite satisfactory. It didn't leak, had good battery and juice economy and my lightly flavoured juices tasted fine. It also has two voltage modes, direct and constant, which are of little interest to me (or possibly anyone), and also low voltage protection. I would unreservedly recommend the eGo ONE TFTA for newbies, simply because it's simple, it works OK, it has AFC, and works straight out of the box. Just add a drip tip!
