I bought the Easy 902 from cigeasy.com last Friday and I received it this past Monday. So I've only been vaping for 3 days now. I'm understanding that this model is the same thing as the KR808D-1 or other names as: Vapor King, Nebula, Vaperello, DPVP9, Fusion, and Zeus. I've had great vapor results from this little thing but today it started giving less andless vapor. So I got online and started doing my searching..... This model uses a cartomizer and I watched a video on how to refill it using the 'condom' technique. I did it, let it sit for 30 minutes... and still barely any vapor. I want to get as much use out of this cartomizer as I can before I chunk it and start with a new one. I thought maybe it was the battery so I switched it out and still, the same thing. I left my other cartomizers at home and I'm stuck here at work for a few more hours. I'm really anxiou to get home so I can try a new cartomizer and see if I get a good vape. I am hoping its just that I need to replace the cartomizer and not that I just bought a crappy E-cig. I'm so glad I found this message board so if anyone has any tips or tricks or any suggestions, please add your 2 cents!
