This was my first vape and I am very disappointed. When I first received it and followed the instructions on filling it. Leaving it to stand it started to leak. I changer the filter and shook it as advised and the issue was still there, however, it was only mild as long as I kept the intake air holes mostly closed. I persevered with this for 3 - 4 days but then hot fluid starting spitting out on to my face and in my mouth. Not wanting to invest any more time buy more filters i have decided to leave it. I also did not receive anything to register it so i felt a bit lost as to where to go . overall disappointed.
