Review on 🐠 Betta, Bowl, and Aquarium Hydor Slim Heater by Melissa Paige

I was a bit skeptical about buying this as some reviews said it electrocutes fish. But I needed something small for my 1g tank. I bought a 4W round piece and even though I buried it under gravel and had an artificial plant on it, it keeps my water just under 80 degrees. The size is suitable for a small fish tank. I don't like how the cord comes out of the pillow, you can't push it tight against the side of the bowl. And I see that smaller bowls can overheat if you don't bury the heater under the gravel. But it works perfectly for me and so far there have been no technical problems. I hope he doesn't let me down for a long time.
