Just a head's up, Cobalt Aquatics is kinda new on the block, so I gave them a go with trying their EasyTherm 75 watt heater. I purchased it October 7th 2014, and it died last week, first spiking a high temp in the tank, then dying completely. However, it has only taken me 3 days to get a RMA authorization from customer service, which is not terrible. I'll update once the process is complete, with the outcome. This was a heater on sale for $41, so I am none too pleased it's dead within 6 months. Just posting in case anyone is considering this company or a heater from them. Anyone else purchased their products and had to do a RMA? I'm curious as to how long this will take. I have no heat in the tank now, and it's snowing outside.
