Marina Floating Thermometer

I purchased two and each shows a different temperature (probably both wrong). The difference is greater than 2 degrees Fahrenheit. Obviously quality control does not exist. It seems that that paper part with those numbers are attached in a wrong position. Since it is in a closed glass cylinder, nothing one can do. If you are looking for acceptable quality, look elsewhere.

Work, but not great. Doesn't come with suction cup. I hate it, but return it will cost more than the thermometer itself. I guess you get what you pay for. Won't buy this one again for sure

I bought a lot of these for science experiments (making solar ovens). I pushed them beyond spec, by heating them in the air, and one melted. Another broke when my son dropped it.

As a basic thermometer, it's fine. Floats well. Numbers a bit hard to see

Glass jacketed so nothing to hold moisture and nothing to promote algae or mildew growth. Small, unobtrusive in pool and easy to store when not needed. Accurate and fairly easy to read although scale is marked in 2 degree increments.
