JOUJBAIL CF-531
Executive Summary: This budget-friendly cooler is a great temporary fix for a hot desk, but its lifespan is cut short by internal moisture and mineral buildup. To get your money's worth, you'll need to be diligent about using distilled water to avoid a "disposable" outcome within just a few months.
The fan motor works hard and can start buzzing if dust gets into the tiny moving parts. This usually sounds like a tiny lawnmower on your desk after a few weeks of heavy use.
Since the water is so close to the power board, there's a high chance of "invisible rust" causing the unit to stop turning on. It's the primary reason these units end up in the bin prematurely.
The plastic shell is decent, but constant contact with water minerals can cause it to become brittle or stained. You'll notice the vents might get a bit "crunchy" or hard to move over time.
