Love this forum almost as much as my Grand. A few questions that I didn't see answered elsewhere - go ahead and slap me if they were answered somewhere else. I'm using my Grand with a 510 cart. I've got the squeeze down now, but sometimes I get some liquid on my lips. Are you guys using drip tips to overcome this? If so, can you point me to what you like as REOS doesn't have any for sale on the site. After a month or two, I'll jump into rebuilding atomizers, just enjoying the ride right now. I bought cheap batteries *18650s, but am going back to Robert's recommended vendor to buy the good ones. I offered to buy 2 of my co-workers REOS mods so that I have a chance to work in a smoke free workplace. For those of you have both a Grand and a Mini (my employees want Minis), are there any discernible performance differences (with the exception of 3ml vs. 6ml and battery time)? Lung function IMPROVING after 10 days and my wife & kids love that I DON'T SMELL! I'm also a tinkerer and want to know if anybody else recommends add-ons (i.e. drip tips, cooler looking cartos, etc). Thanks to Robert, Ray (guy in Florida that demo'd unit) and this forum. Finally, where can I get that awesome code for my bottom banner (REOS...quit analogs, etc.)
