Looks like this thread's pretty much done with but would just like to give my 50 pence (I'm a UK member) on the Realis- this was my second e-cig before I moved onto a 510 and I really loved it. As a noob vaper, it was a great one to start with as it really looked and felt like an analogue, unlike the huge Gamucci which I had before. I got a PCC with it which meant I could charge it up wherever, whenever which was also great.
The only two issues I really had with it were that the (empty) cartomisers were quite expensive and didn't seem to last for more than about 4 refills- I tried reviving them in hot water and drying but didnt have much luck. The other problem was with the batteries, which are so small that you don't get much vaping time before you have to recharge. I would recommend getting at least one spare battery so that you can vape one while the other charges.
Finally as with some other carto-based models you need to be careful about not overfilling the carto as the chances of getting a mouthful of e-juice are pretty high if you do. Fill 4-5 drops max at a time and leave the carto mouth-end up for a minute or so before you vape it to let the liquid settle. Also a thin VG mix or straight PG seems to work better for refilling than thicker liquids
Hope this helps
btw I will probably do a full review of this model on my homepage/blog sometime soon as I liked the Realis a lot - will post when I'm done.
bbtw I just found the realis fits my regular 510 mains charger which means now I can charge 2 batts at the same time!!
