UP to now many kinds of electronic cigarette device come out,such as 808,901,510,510-T,ego/ego-T, eGo-C, Riva-T,MOD. Here today I would like to talk about ego-T.In my personal opinion,ego-T can be considered a start of the bigger battery, a start of big tank,also the milestone of the electronic cigarette device development history. As everyone knows, tank is short for T. In the development of tank system,before ego-T, there is also 510-T.But as a matter of the fact, the tank cartomizer of 510-T is only about 0.7ml which is so small capacity so that users need to refill frequently. Ego-T is better than 510-T, it has about 1.2ml tank cartomizer, which can create 200 puff. We do not need to drip constantly because it is enough to lastaverage user for a half day.The tank is transparent so that users can know how much eliquid left. The second which is important is the battery capacity. Users should consider the battery, how long it can last. Before ego battery, those batteries such as 510 battery,808 battery are all lower capacity for example 280mah. However, there are 650mah, 900mah and 1100mah ego battery available which is a excellent news for the smokers. The users dont need to charge the battery frequently. Another new development is on the button.Simply press the button 5 or 3 times and it will automatically turn off, to reactivate, just press it another 5 times. This safety feature is a must when your e cigarette is being stored in a pocket or bag. The last one but also very important is the cost. Perhaps many people think the above mainly talks about the new development,compared with the old products such as 510 but in fact now there are some tank system device who come later. But please dont forget another thing, that is the price of ego-t. Usually it is cheaper than the new one like riva series products but it also can create big vapor and even throat.So, ego-T is one high quality with the most favorable price. You may have a try, especially you like lower cost.
