Review on 🐠 EFFICIENT EVERSECU 72w 110-240v Aquarium Water Chiller Warmer/Cooler - Advanced Temperature Control for Fish Shrimp Tanks, Marine Coral Reef Tanks Under 20L/30L Capacity by Tessa Dolan

To be honest, this is complete nonsense. I don't usually write reviews for things, but this is totally false advertising. It worked for me in a 5 gallon bucket that wasn't even full, maybe 2 gallons of water, and the temp had dropped 2 degrees in the last 24 hours. Yes, and not to mention that it also leaked everywhere to begin with. The supplied hose is not sufficient. Enough pipes for an entry point, but not enough to come back. I tried using my own whistle which ended in disaster even though it was the same size.
