Being a newbie I'm unable to post directly to any specific link, however I'd like to thank Isaac of Ikenvape for all of his help and very quick responses to my email questions. Having limited experience to ecigs, my previous model lacked the gratification I was hoping for. Isaac was so helpful and suggested a KR-808D-1, which I'm extremely satisfied with. The larger battery provides me with a lot of additional time for vaping. Carto's are easy to fill and re-fill too. Delivery of my order came very quickly. I'll be a retuning customer. Thanks again for outstanding customer service. 
I've ordered some cartos from Isaac and they were very reliable. The nice stainless steel ones.................nice and shiney
