### ⭐ Do not buy this
*by B***N on October 4, 2024*

Worked fine for a few weeks, I came home on my lunch. Found a house full of smoke and the ato plug shorting out inside and on fire. I have damage to my stand, my tank, and my wall. This has absolutely nothing to do with moisture getting to it. Below my tank is completely dry and I have drain loops in all my cords. I am very lucky I came home when I did or I would need a new house.
