I've tried some different digital thermometers for my saltwater aquarium, but this is definitely the best looking one. It's blue led lights are perfect size and very easy to read. In terms of functionality, it's very accurate. I'll recommend this product to others.

This was the first piece of equipment I have for an upcoming nano reef build, I decided that I would give it a test run in the kitchen sink, mostly just to check out the blue numbers that the unit has and to see how steady/accurate it would be. <br>It is the usual tamper-proof plastic enclosure the the unit is packaged in so get the scissors to get it out. Basic instructions are printed on the back label for those that need them. Pull the fake number plastic thingy over the display, install LED unit in tank, and plug it in. There is a small red LED on the plug. Make sure your power strip/ power source is close so you can get your drip loop made.<br> Now I say that because that is the only downfall I see with this, is the power cord could be a foot or two longer. The test in the sink has been satisfactory, temp held steady for over a hour, no blinking of the light. Sensed change in water temps quite well also. Lengthen the power cord and I feel like you would get 5 Stars then.
