Review on 🐠 DaToo Aquarium Thermometer Sucker Mount - Second Generation (Update), 1 Year Warranty by Jose Schweigert

The simplicity of this thermometer is good, but there is a design flaw and this is where the suction cup connects to the main thermometer. The suction cup loses its shape and just stops sucking and floats around my aquarium so I have to keep holding it against the glass of the aquarium and after a few minutes it loses the suction cup and floats around my aquarium until it becomes brittle and does not break. It's really good, but the placement of the suction cup and that thin gap between the main thermometer is really an issue for me because of what happened. That's 2 stars for a working digital thermometer and -3 stars for poor design.
