Review on Hydor Slim Heater for Bettas: Optimized for Bowls and Aquariums by Javon Kulik

Hello, I just wanted to say a few words about this product and for the price it's actually very good. The only thing I want to differentiate about this product is that I wish it had a way to control the temperature. I wasn't sure at first if I should buy this product but I went ahead and bought it. It all feels like strong plastic but flexible material. It has a source pad that you place under the rocks in your tank. The source pad has a curve in the middle and an extra piece of plastic underneath. I'm not exactly sure why. Chord 10 feet or a little less. It sits well under the tank, it doesn't move because there is a piece attached to the belt for it to hook or unhook on the side of the tank. I prefer to use it in a tank. It will be shipped in this plastic and cardboard case once you receive it. It matches the picture shown. The temperature changes gradually throughout the tank. I have mines in the middle of the tank. A 3.5 gallon tank works very well. You'll need to monitor it every few hours in case the tank gets too hot. I just wish I could choose the temperature. Many Thanks.
