Review on 🔥 Orlushy Submersible Aquarium Heater: Adjustable 30W-500W with Free Thermometer for Marine Saltwater & Freshwater Tanks by Marina Smith

In the last few months I've bought 2 other Revain adjustable heaters and both have been somewhat faulty. I ended up using both at the same time to efficiently heat up my 15 gallon tank. I was really hoping this would be the last heater I would have to buy. First, this heater is small, but it is good. It's heavy and seems much stronger than others I have. The thermometer reads exactly, maybe 0.3 degrees warmer than at home. The heater itself is off a bit, which isn't a big deal, I just turn the dial just below 78 and the tank stays at 80. That might be because the tank is also 15 gallons, so 100 watts might be a bit too powerful for it. But I'm happy no matter what. Will update in the future if my mind changes.
