Works as advertised

So far works as advertised in my 90 gal cube. Put it in the water for 20 min (unplugged), plug it in and set your temperature. Overnight temp was within range. Easy to see numbers for us more mature aquarium keepers and instant verification from across the room with the colored background LED (always on sadly), blue is colder than set temp, green is within range and I assume red is over set range (have not seen that - thankfully). Update: 10 days in and the aquarium is as stable as can be. The temperature does vary about +/- 1 degree during a given 24 hour period but that's to be expected as the temperature of my house easily varies 20 degrees (F) in a given day [I live by the beach and the windows are open 24/7 in the summer]
