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

Good when I got it. I compared with two other digital thermometers. < 7 months it suddenly shows 8° COLD. Ok, winter is here, so I turned on the heating first (like every year this time). But when the temperature didn't rise much, I tested it with others and now it's MUCH different. Even when I tried to put it back in the tank, the suction cup wouldn't stick to the glass. When I tried to squeeze it a little harder it broke. Now it's unreadable AND just floats upside down (can't see readings). It no longer makes sense - in less than a year.
