I bought this in 2015 (!!!) as a joke, just to mess around with a friend who was opening a shop at the time. This little mod is simply unbeatable. My dogs (Dobermans) bit it, a truck ran over it the next moment it fell on the asphalt (for the umpteenth time), the screws of the top lid broke and it got crooked, and I'm holding it together with a rubber band. I've demolished it to buy a trendier one, which I threw away after 6 months and started using this badass again. It has endured the falls of its life. Forgotten in the rain in the garden, buried in the soil once. It has fallen on cement, on insulation paint, in water. It has been through hell in my hands and yet... It's either immortal or has seven lives. I guess I stumbled upon a good batch. Now I'm looking for the same thing again, so I don't go around with this one that has reached the limits of its color wear. Although I don't think I'll find EXACTLY the same one. This one, in particular, was made for me and me alone. Devilishly durable!

Although late since I accidentally found myself on the page, I will evaluate it since I see that it is still being sold. It is worn out and broken in the drawer. I bought it three years ago in a quick purchase because I completely ran out of mods. I used it back then with the eleaf gs tank.
After a week of admittedly excellent performance in everything, it started to have some occasional issues. It would fire, measure time correctly, but wouldn't supply power to the atomizer. Initially, the problem occurred about once a minute and once a day. As the days went by, the frequency of the problem increased to the point where it became annoying. I went to the store (Agrinio) where the owner replied that such a problem has never been reported and it's just my imagination. After a few days, I brought it back more forcefully. He was forced to keep it and check it since it didn't show the problem there. I took it back the next day, saying that it didn't show any issues. For the next week, the problem worsened even more until one day I was near the store and it presented the problem to me. I brought it in front of him... it turned bright red... I will send it to Athens for service. After ten days, it was returned with an indication of a faulty battery and replacement. Nonsense... I took it and as we were talking and vaping, it happened again in front of him. With all the hassle, he promised to send it to service with the indication of replacement. After 20 days and no notification, I went and chewed them out... it still hadn't arrived, etc. I left threatening that I would return in a week and the world should find a definitive solution. Meanwhile, I had bought another eleaf tc 60 and it worked perfectly. I still have it, immortal!!!
In the following week, after a little fuss, they replaced it with a new one. I took the new one and the same night, while going out, I thought let me take this with me tonight for a change. It worked normally for about two hours and suddenly showed "no atomizer" message. After checking it with many atomizers and it still showing the same issue, I gave up on it and it's still there... a relic. Two tc 40s, both broken. I wasted my money and time, and also dangerously tested my patience with this particular mod!

I bought it because of its supposed long battery life and to try out the temperature control. It's impossible for it to be 2600 mah. The same thing is said by experts who have tested it. The temp control didn't impress me in terms of flavor, nor did I see any battery or e-liquid efficiency as eleaf claims, so I only use it in VW mode. The battery doesn't hold up well with high-powered atomizers with low resistances and hardcore vaping. It's preferable to use something stronger. I realized this after trying it with the Melo and 0.3/0.5 coils. They drain the battery and e-liquid like sponges. The same goes for the Ni200 0.15 temp control. And not the flavor I wanted. Now I use coils above 0.75 and I have better flavor and more battery life. I don't regret buying it. It's small and convenient and meets my needs, but it's not suitable for someone who wants intense sub ohm vaping. It's more for mellow cigarette-like experiences. Also, it's not true what someone said about it only accepting one atomizer for temp control. They must have been a bit confused. Any atomizer that accepts nickel coils for temperature control will work if you put it on top. Update: After 5 months, the battery gave out. The screen works and recognizes the atomizer, but it doesn't provide power. You take off the atomizer and it continues to behave as if it's still on. I didn't expect it to last a lifetime, but not this short either. I believe it was an isolated issue and not a general one. Thankfully, I sent it back to the store and to their credit, even though the warranty had expired, they acknowledged the problem and replaced it with a new one that works perfectly fine.
