I've owned 3 Zelos kits. The Nautilus 2 tank has really good flavour and the top fill is really convenient but I've had issues with the locking mechanism meaning its difficult if not impossible to separate the glass for cleaning.
On all 3 Zelos batteries the bottom metal plate came loose after 2 to 3 months use. Tightening the screws works for a few days then its the same story. I definitely wouldn't recommend this kit.
