Been using it for a little over two weeks now. I'm really surprised at how well it delivers for such a tiny device and I mean tiny compared to a standard 510. I use a lot of cig like stuff during the day and this has replaced them. The first thing I did was up my nic and pg thinking I'd need it to get a decent hit and satisfaction out of it. Wrong. I completely underestimated it. Using it as intended which is to vape a little while and put it back in the pcc it maintains it's voltage quite well and kicks the ego c atty as well as an ego battery keeping consideration for auto vs manual in mind. My preference is auto when I'm out and about or busy. As for it's size and thinking it's only 90mah, the reality is you're leaving home with 1,090 mah. Size really doesn't matter. The recovery time when you put it back in the pcc is short. I've only completely drained it once. Another good point is hands free
vaping. It's light enough to hold in your mouth while performing tasks that take both hands. One thing that is necessary if you're going to use it all day is buy more
tanks. You can't put too much water in a nuclear reactor. I've got an old carto case I put 5 in and stick in my pocket and one on the device for a whopping total of 3ml. They're quicker and easier to change than standard cartos. Pop the empty out and the full in in seconds. If I wanted to find anything at all to whine about it would be the
tank size but you get used to it and fill them all up in the evening. I'm still using the first atty which I've cleaned and dry burned once and it's performing almost as well as new so they last well. I wouldn't bother with lr as it isn't necessary and will prolly shorten the charge life. In the evening I use my bigger stuff for the most part as I tend to chain vape while I'm watching tv or on the puter but if I start doing any activity at all the eRoll is my goto. Never thought I'd see the day but it's here.
