## Customer Reviews

### ⭐⭐⭐⭐⭐ accurate, convenient
*by W***O on May 12, 2025*

Great so far. Temperature reading seems to align to that of the hot tub. inside monitor makes it much easier to check temperature before changing to use the tub. Great product.

### ⭐⭐⭐⭐⭐ It’s a snap!
*by D***E on May 11, 2025*

Couldn’t be easier to set up and use. I love the convenience of seeing the pool temp without going b outside. I’m sure there’s also other applications for this lovely product.

### ⭐⭐⭐⭐ Pool thermometer works well
*by K***N on May 12, 2025*

When I first received the pool thermometer the temperature reading was not close to the actual temperature. After a couple of days it settled down to be within a degree or 2 of the actual temperature. So far it is working well and it's nice to see what the pool water temperature is without going outside.
