I bit the bullet and bought a new Aspire Cleito 120 tank. I am feeling like I just wasted my money. This thing does not work for me. I filled and primed it. Took about 4 drags. Not near as much vape as one would expect from a sub-ohm tank like this. On the 5th drag nothing. No vape but it got really hot. I took it all apart cleaned it and re primed it. again the same thing. I then replaced the coil and tried it again. This time it worked for about 6 Drags then nothing. I unscrewed the top and put it back on. Wow it worked for another 4 to 6 drags then nothing again. I am using it on a 60 watt mod that is good for down to 0.05 Ohms. Turn up the wattage does not make any difference. I put it on a friends Smok Stick V8 and it produced a little better vape then the Smok stick died. I mean Dead. Now the light flashes 5 times any time you hit the button even with the original tank on it. I put the smok stick V8 tank on my mod and it works good. I am pretty sure the Cleito fried the Smok Stick. My mod show the coil resistance and it is what it should be. What else to try? Or is it just time to try to return it.
