I'm in the middle of cycling a new aquarium, but wanted to keep a check on my water temperature, to monitor the new heater. I could have opted for an expensive digital model, but didn't see the point in spending so much money, when this does the job adequately. I could have gone for a stick on strip, but don't like the way they look, so I opted for this thermometer.
The graduations are easy to read whilst in the tank, I've popped it in the corner at the back where from the front its hidden by a plant, yet easily readable from the side. I particularly like the yellow background, as its easy to read the temperature in the tank. The sucker keeps it in place, and does its job well.
All in all its a tidy unit that gives peace of mind. Highly recommended.
