Review on IOAOI 50W Aquarium Heater for up to 20 Gallon Tanks - Shatterproof, Suitable for Marine and Fresh Water - Engineering Plastic Tube & Stainless Steel Inside - Adjustable Temperature by Jennifer Hernandez

We love this brand of aquarium heaters. We have five in total [of varying capacities] and they have always been reliable, accurate and durable. Cool packaging even. They're also the nicest heaters we've ever seen. The all black finish is very nice. Not to mention if you're worried about exploding, cracking, or shattering glass heaters, the metal construction is excellent for peace of mind. The included suction cups are pretty standard; ours seem to be working decently enough and haven't lost suction or gone bad yet. Unfortunately it seems that some of their other heaters are no longer available. We hope this brand never disappears entirely because we will continue to buy their heaters when the need arises. Fiction.
