Review on 🐠 InkbirdPlus 300W Submersible Aquarium Heater - Titanium Fish Tank Auto Thermostat with LED Digital Temperature Readout and External Controller - Ideal for Saltwater and Freshwater Aquatic Environments by Melissa Brown

I've been using this heater for a few weeks now and it's holding the temperature well. I didn't connect a controller to this tank to control the temperature, but every time I check the temperature inside the tank with a thermometer, it agrees. The heater is incredibly easy to set up, you simply press a button until your desired set temperature is displayed. The tube itself looks well built, but some parts of the heater feel cheap. The button control box seems cheap, there's also a small black cover that runs where the wires enter the heater and it doesn't fit very well. When I first got the heater I thought the little cover on mine broke off but I was able to put it back on but it doesn't seem very secure, it would probably be better if they just taped it on. Both of these complaints are minor and not surprising for a budget heater. It doesn't particularly matter because once you install it, you'll probably never touch any of these parts again. I would like the heater to be a bit shorter to make it easier to fit my pan, but it's a reasonable length. I have shorter ones, but I've also had significantly longer heaters of this capacity. Before purchasing, make sure the heater will fit where you intend to put it. Overall, I like it so much that I'm going to get a second heater for my 125g reef tank.
