I purchased 2 Platinum Rivas a couple weeks ago. The first week one rocked and the other was sub par. I started dripping the juice (3-4) right onto the atomizer. At first it was great but now I have to puff on it like a pipe to get it going and even then I'm not getting the vapor coming out like it was before. I'm using the same liquid. Could it be a problem with the atomizer? Have I already broken both Rivas?
