Review on Finnex Digital Temperature Controller Heater by Bryan Gibbons

Like many others. Apparently this temperature sensor is not calibrated. That's about 1F too low. In addition, the temperature sensor has a very short cable for large tanks. Otherwise it looks like it will work. UPDATE: Ironically, as someone else mentioned, this failed after 13 months of use. I'm pretty sure the temperature sensor is the defective part. I have contacted the manufacturer. They are quite rude, asked for my receipt and never spoke again. They should work on their customer service skills if they want to keep customers. Guarantee 6 months. After that, they expect you to ship it to them for your own money and wait until they find out how much the repair costs. I ended up buying a BTC211 byte temperature controller which was a bit more difficult to set up. But I'm willing to pay almost twice as much for a quality product.
