I just received my new Plato yesterday. Overall I love for form-factor, the auto-rotating screen, the 'look', etc. But the device leaks! I drained and checked the o-rings, once did seem to not be set right, so I did adjust it. I vaped for about an hour, and did not notice for sure any leaking. A couple small smears of liquid I was not sure if was from before in which I perhaps did not clean up all the way. I put upright on a napkin overnight... come morning about 2/3 of my juice was no in the napkin. O-rings all look good. I love the mod but simply cannot use if this think is gonna leak!! If I cannot find a solution in the next few days, then I'll be taking it back for a refund.
One thing I do not like is that when tightening the coils down is that there is really no way to know if you've got it too loose or too tight. I did find information about how the lower o-ring should 'disappear' into the bottom seating section, but once it's gone you can still tighten quite a bit. I think this tank system could have been better designed. Still, if I can resolve the leaking, then it'd probably be my everyday mod.
