Okay so I have been using the Ego AIO for the past couple of days now and I have to say if this device had been around when I first started vaping it would have saved me a TON of money trying to find the perfect setup! It's super simple to set up. The flavor and vapor are better than I expected, and battery life isn't bad at all! I charged it soon after I set it up and it was fully charged in less than half an hour. I can't tell you how much less because I wasn't paying attention to when the light went off, but when I did check it at the 30 minute mark it was fully charged. I haven't had it back on the charger yet and I just filled my second tank of juice. The lights are fun to play with. It is much brighter when it is charging, but I can definitely see it while vaping. I have it on the green light right now.
The childproof cap on top is great! You just push down and twist to remove the cap to fill the tank. the air flow control is a little hard to get used to because there is nothing to gauge where the air flow actually is (open or closed). This is absolutely a MTL device, though. It's a tight draw no matter where I set the air flow, but it's not uncomfortably tight.
The device is small and lightweight but it feels solid. I was not super convinced that it wasn't just a flimsy plastic case until I used it for a while. It's much more rugged than it feels in the hand.
Of note, this is not a VW, VV or TC device. There is nothing to do but fill and vape. I have no idea what the coil is actually reading at, but the vape is on the warm side. Heat does transfer to the top cap but not to the drip tip, and the box does not get warm at all.
All in all I think this is a wonderful beginner mod for someone who is trying to make the switch. It's easy to set up and use, the flavor and vapor are great, and it has that little something extra with the 7 different LED colors for the window. Here are some unboxing pics and a hand check!
