i have an ovale elips that i keep in my purse and use while out and about. the ovale works great for being so small, i use the LR atty on it and it rocks for what it is. i haven't had a leak or anything but like another poster said, the
tank does get condensation on it which you just wipe off easily. great little e cig that i will continue to use even when my provari arrives. they also make a generic version of the ovale for less money so maybe check that out if you didn't purchase something yet.
