I just recently bought another Da Buddha (my old one was confiscated) and it has given me problems since the beginning. Immediately upon setting it up I noticed that the heating element was loose. Also, sparks came from the heating element about five times while using it. I called 7th floor today and they suggested I send it in so they can replace the heating element. The only problem is, the piece is a little dirty. I've only used it 3 times though. How do I clean the DBV sufficiently so it will make it to 7th floor without any problems? I will be using USPS to ship it. I have removed the heat cover and will probably soak it in alcohol. What else should i do? Anyone else have experience shipping their used DBV in for warranty?
