I changed to the .4 ohm coil that came with the plato. I checked to make sure I installed it properly. I watched the video "10 tips for plato". Now it is constantly leaking from the air flow valve. I see where there are a lot of posts concerning this problem with plato. I contacted the store I purchased from and they said they could not refund since it had been opened but I could ship to them and they would check it out and if leaks then will send another one. But sounds like it is just a problem with plato. Using Bypass on unit and e-liquid is 70PG/30VG. Would appreciate any advice/suggestions. So frustrating. Wasting soon much e-liquid. Messy on hands too when holding. Have not had out in hot car. only in house. last night sat it on paper towel and this morning paper was socked. Help please.
