I have been lurking here for about three weeks now and have gained a wealth of knowledge. I decided it was time to join. I only have experience with the KR808's, three different kits. I have been vaping for one month now. I only started vaping to see if it could get me through the work day, and it has done that. I have found that I enjoy it more than analogs most of the time except for first thing in the am., after meals and one at the end of the day. I have gone from smoking twentyfive to thirty to about seven a day. When I first started I was using Chinese PG only liquid, which made my throat sore, but have since changed to at least 80 PG /20 VG (Domestic) mix and have not had that problem since.
