I've seen this happen to me many times with a crooked clearo. what I have noticed is that sometimes the base will become loose after awhile and may start wiggle out a little and it's not noticeable until you screw it on. I just placed on hard flat surface and pushed the main tube back into place and everything lined up perfectly and no leaks, I've done this with the i16 and the kanger t2's my most popular clearos to date, but mostly it's the top feeding coils with the secured base, that only the mouth piece unscrews and u refill from top.
I just received my vamo v3 and its my first mod, so I have nothing to compare to but I love it and I like the swirls in it, seems to be the least liked thing from what I've read. it provides a nice grip and I actually like the way it looks. it seems like a major improvement over my ego twist, but just have to get used to vaping from a night stick! this thing has some weight to it and with the 2200 m/a Samsung 18650 bat in it it's quite long, thinking about scaling down on bat just to remove the extra piece of tube and shorten it up but well see...
I really like the idea of just replacing old bats without having to buy a whole new ego twist, which worked great, I'm hoping to save a little a money when replacing old bats as opposed to buying a new twist( a pair that is) every so often. I also love the display and functions of my new vamo 3, but I can't figure how to see the battery level? I change the display in the menu to show the batt level and it just shows volts, watts or ohms. it says that it will tell you when the batt is low but can you check at all to see where you at before then? I haven't drained my first batt yet so I don't really know if there is even a batt indicator.
