110V-220V Adjustable Temperature Thermostat Heater Rod 25W/ 50W/ 100W/ 200W/ 300W Submersible Fish Tank Water Heat

Normal warmers. When the test in a three-liter bottle, showed the error of the set temperature of about 0,35 °, hysteresis of 0,5 °, which is very good. The second showed a greater difference, but this is probably an error due to a small volume and the thermoregulator did not have time to work on time. In any case, I use homemade electronic as a thermoregulator, with very high sensitivity and fast reaction.

Arrived in three weeks with tracking. Box and quality packing on top. The day works, the declared temperature is still holding. It looks very reliable. The aquarium is prepared with a thermostat. Waiting for fish. I like everything for now.

The heater came quickly, whole, heats the water to a certain temperature and turns off, then if the degree of water dropped again turns on, until the Hood how much will last I know't
