Customer Reviews
“Finally, a tank sensor that actually works! No more guessing when the fresh water is running low. The app is clean and the sensor was dead simple to install.”
“We've been full-timing for 3 years and tried every sensor on the market. OraRV is the first one that gives consistent, accurate readings. Worth every penny.”
“Installed on all three tanks in under 20 minutes. The Bluetooth range easily covers our 35ft fifth wheel. Highly recommend for any RVer.”
