No i fill it from the bottom. Not a big deal but i just dont understand it cause the air hole is up from where the juice would be. Are you having the same thing happen with yours?
No don't have the same problem but it did happen to me one time.When filling with the syringe,as the syringe emptied i did not get the needle out of the R91% in time,and it got a shot of air inside the tank.As soon as i got the fill screw in and turned it up right,i got liquid out the air intake hole.It kept on leaking out the hole for about 5-10 minutes and finally stopped.
Just be careful when filling not to get air inside the tank.When vaping the same will happen.If you happen to breath into the mouthpiece,it will leak.
