Pardon me while I gush just a bit ... I'm new to the vaping, less than a week in ... I did about a weeks worth of research before I made a purchase and in the end I followed the advice of the fine people here at ECF and I order the mid range starter kit from SI with a 78mm batt and an extra pack of carts. I ordered late on a Tues and my order arrived Fri (Awesome!). By Sat I was making an order for a 650 X2 and a couple X2 clearos to get my hubby started as well as a new manual 78mm for me and couple of the nano clearos just to try out, they arrived yesterday (again, awesome!). Now, we're fortunate to have a couple of B&M vapor stores here in town but they cater to the 510 crowd ... However, I am trying out some juice from them. But, I went with SI because of the excellent CS you all talk about here ... Good service is very important to me. So, I made a rookie mistake with my hubby's X2 and didn't click it on right ... I just couldn't get it to work ... Bummed ... I pulled up the website on my iPad and used the Live Chat feature and "spoke" with Heather who IMd a link to a YouTube on how to turn the thing on ... I tried again and eureka! Thanks Heather! To conclude (sorry for the book) I am super pleased with SI and will be a loyal customer. My hubby is fully on board and already wanting more batts and clearos ... I love my both my batts and the nano (one was a dud but the other works stellar and I adore it) and will be ordering more, more, more. So, thank you to everyone here at ECF for steering me in the right direction and thank you SI for being a great company with excellent products and service ... We are now a smoke free family. Oh and ... While researching I watched several Mr. Outlaw vids on YouTube ... They're great, thanks for those too!
