I bought this device about a month ago and was really excited about it because all the reviews stated Aspire fixed all the issues that their competitor had with the Nebox. Was really happy with it until after the initial experience. IT DOES leak from the air control at the bottom and is an absolute mess to change out coils and with that ridiculous little tool. another thing noticed is now the lack of flavour even though I just changed the coil. My first device had a nautilus mini tank which was great first but then ceased to work 2 months later. Not happy with aspire don't think I'll ever buy another product from them again.
