Review on Advanced Aquatop Quartz Glass Submersible Heaters (50W-300W) by Mary Hunt

The heaters work great in my aquarium. I'm very glad I took the risk and bought three at once. The visible temperature dial and easy-to-reach adjustment knob on the top are two great features of this heater in this price range. The heater is well made and doesn't look cheap at all. Such a heater can easily retail for 30+. I've only had them in 3 of my tanks for a couple of months so I can't say how well they will hold up but given their good workmanship I expect they will last for many years. Great packaging and super fast shipping. I recommend this seller.
