I'm new started vaping on the 16th of March. I purchased the Riva from Vapor Junction and am happy with it. I tried the EM LR 510 atomizer but it shut down two fully charged batteries so can't say I would recommend it. Thus far I am 8 days smoke free so all is well. Have tried several menthol juices and have found that the Salem at Indy Vapor is very pleasing. I am into Modding Surefire type flashlights so I can see many mods in my future. I am a big fan of the 18650 Lion Battery with 2900 mah Anyone looking for 18650 batteries try lighthound. The AW cells are awesome.
