Hygger Aquarium Heater 300W/500W/800W/1000W, Submersible Heater for Aquarium with Digital LED Driver and Intelligent Heating System for Fresh and Salt Water

Been a year an still working . Heats a 800 gallon steady a 80

Lo compre para un acuario marino mediano de 280 litros....chulada de calentador, hace correctamente su función al calentar el agua y medir la temperatura, lo único medio malo es que solo puedo configurar la temperatura en grados Fahrenheit y no tiene opción para grados Celsius que aquí en MX es lo que tenemos, pero como tengo un termómetro alterno para medir la temperatura y este si trae ambos pues me facilita la conversión y confirmar la correcta temperatura, su tamaño es un poco grande validen el espacio a donde ponerlo y su color anaranjado hace que resalte, pero si tienen opción de colocarlo en un filtro externo fuera de la pecera seria ideal. Lo recomiendo, a mi me gusto y funciono bastante bien....calienta el agua muy rápido.

I waited a while before writing this review, as I wanted to make sure that it was long lasting and durable. I love the ease of set up, operation, and the constant display of the current temperature. We will see how durable it is this winter. It is such a great price, I will get another one to take some of the strain of this one this winter. Update: This is my third of these. The first was a test. It worked great. So I ordered another since a different brand heater burned out. Then I purchased this one for another tank. All are running now. I expect they will give me years of good service. I like the current temp, set temp, and wattage display. Very good design.

Gran marca y de excelente calidad, muy profesional y fácil de utilizar.

-TL;DR- Stop searching, buy Hygger, be happy. - These heaters are robust enough to keep my Golden Butterfly Koi pond a balmy 70°F all through the winter; even during extended drops as low as -10°F ambient air temp! I can walk outside with 6" of snow on the ground, and there's my pond, looking like a steamy, little oasis, with very happy, active koi swimming around. I have always been very pleased with the premium design and materials used in their products. For the first time ever, I can comment on the customer service they provide. I have purchased 3 of these 1000W heaters, among other things, from Hygger. I've only ever had an issue one time, and that was recently when one heater stopped working, for no apparent reason. I contacted Hygger via email and they responded so quickly, that I was shocked. After some troubleshooting attempts it was decided that the heater had malfunctioned. It may not have even been due to poor craftsmanship, it could have been a random power surge or whatever. Heck, sometimes stuff just breaks. Regardless, the customer care team immediately jumped into action and here I am, less than a week later with a brand new replacement heater. That's what I call amazing service. Thank you, Hygger. I have used a wide variety of Hygger brand products over the years, from indoor fish tanks, to outdoor koi ponds; I don't even bother searching beyond Hygger, and I recommend them to everyone I know.
