Review on 🌡️ Aqueon Adjustable Preset Heater by Julie Blanford

Update: The heater was installed within 3 days and the temperature of my aquarium went up 1 degree to 75 F. Back. This 200 watt heater replaced one of my failed 100 watt Tetra heaters. For four days another working 100w tetra was struggling to keep my temp at 74 so I bought this 200w tetra to get the temp up. This heater turns on for about a minute and then off for about 5-10 minutes while my Tetra keeps running non-stop. About six hours after installing my temperature is still 74 F with an ambient temperature of 72. If the temperature hits 76 by morning I'll be happy, but so far things aren't looking promising.
