I like my full size Nautilus. I gave both of my Nautilus minis away. Dry hits, muted flavor, and burned frequently. I was using an Evod-V V3 battery. I recently upgraded to an Eleaf iStick 50W and an Eleaf Lemo Drop. I'm in heaven. The full size Nautilus is a great tank. Good airflow. Pretty good flavor with most juices that I vape. The heads are somewhat of a PITA to rebuild. At least for me. The only issue that I had with the full size Nautilus was with opening it up to refill it. Juice gets down beneath the bottom gasket and acts like sement. I was using pliers to open it. A quick rinse of the seal area might help with that. The Lemo tank was a game changer for me. Easy to build on and wire and cotton is cheap. I use more juice, though, because ALL of my juices taste great with this tank. I guess that it's due to more cotton soaking up more juice and a larger coil vaporizing said juice. If you're looking to get a full size RTA, you can't go wrong with the Lemo. My apologies for rambling. Vape cheers!
