  • Exceeded expectations!
Style: Pool Thermometer
Purchased the ThermoPro TP211B, and I’m extremely pleased so far. It exceeded my expectations. I’m using it to monitor my aluminum wood fired hot tub, and it is a game changer! It has made a improvement in my ability to monitor and control the temperature of the wood fired hot tub. I was worried that the aluminum tub sides would block the wireless signal, but it worked great, and I was able to place the receiver display conveniently on the living room table indoors (about 30ft away), and it displayed the water temp flawlessly. The receiver display is nice and big and easy to read from across the room. The system is well designed and transmitter quite rugged. I’ve only used it one weekend so far, so I can speak to long term reliability, but the 1 year warrantee and support appears to be good. I also like the fact that it uses basic AAA batteries. Highly recommended. ... show more

  • Find out the water temp without getting your feet wet!
Style: Pool Thermometer
We were never sure if the water was warm enough to swim, but with this we now can see from the comfort of our home what temperature the water is and if it is warm, comfort or cool. Works really well and we’ve had no problems thus far !

  • Does a Good Job
Style: Pool Thermometer
Good value in a useful product where the temperature reading of a pool, spa or other facility is desired remotely, indoors, for example. We had no way to check the calibration, but its readings gave no reason to be doubted. Just installed--no indication of its longevity, but the internals appear to be very well made. One caveat: keep the threaded ring on the remote sensor tight or moisture may get in and disrupt its operation. If the pool has a cover, we suggest cutting a clearance opening in it to keep the remote unit exposed to the atmosphere, again to minimize the chance of moisture intrusion. ... show more

  • Leaked after 3 months.
Style: Pool Thermometer
A lot of the reviews are from Oct 2024- Dec 2024. We bought ours in Sept. 2024. I love it. It was accurate, no real set up, worked right out of the box. Large indoor display with a magnet(we keep it on the fridge). But was not reading correct in Jan 2025. There was water in the thermostat. We are drying it out and hopefully it will work again. I’m curious to see if anyone else has this issue after a few months?? Update: we were able to take it apart, dry it out, then put it back together. Seems to be good now. We would hate for the water to keep getting in like that because we do love the product. ... show more

  • It's accurate and it tells me pool temp without going outside
Style: Pool Thermometer
It seems well-designed and built to last. We will see. I'm familiar with other Thermo-Pro temperature gauges, and they are accurate. Data displayed in a logical, easy-to-read format. Inside display has a kick-stand and a magnetic strip on the back for flexible mounting options. Thermo-pro uses the good Chinese factory to make their products. ... show more

  • So Far, So Good
Style: Pool Thermometer
This thermometer is working beautifully so far. My last one, a different brand, worked for about a week and then went off and stopped working. This one is doing the job and it is nice to know the pool temperature is accurate.
