I've been using a couple of old eleaf isticks with nautilus tanks (20watt, I think). They've been great, but the batteries are starting to die on the sticks, so I need to get some replacements. I figure I might as well try some new tanks while I'm at it. I don't vape at high wattages or do anything fancy, so recommendations for stuff thats just supposed to be well built and work fine for the average user is what I'm looking for. Thanks.
