HydroTools by Swimline Easy View Pool & Spa Tube Thermometer

smaller than I thought it would be and a little hard to read. But it seems to be accurate. Comes with crummy little bit of string to hang it and the loop is not large enough to put anything better through it.

Made from durable plastic. However, less than a month later, I can't see the temperature because of the alguae, and the product is made a way you can't clean it.

This thermometer works but is cheap plastic. I don't expect it to last long.

It works fine, but the rope don't hold, the thermotmeter falls to the bottom of the pool.

Floated for a couple hours then sank to the bottom of the pool
