  • This is great tool for not having to guess whether you have enough propane to heat and shower ect. No more midnight tank switches.The sensors are also worth the money just to sabe gas if you develop a slow leak. Works great for me!

  • Sensors sync'd up was as advertised. Very disappointed with NO APP available. Have to keep going to play store to get information.

  • Try as I might, the sensors are hit or miss. Q minute nothing, next minute 80%, but moments later 15%. Brand new 20# tanks, nope still not working. Tried on the bbq tank, 10%, 80%, 85, then empty.

  • So far the app is working fine on my Pixel 2 XL... Wish the app had a login and a account were it would store your information and the sensors. Would definitely rate 5 stars if we had a history chart (time vs consumption or time vs capacity left), refiling history and integration with IFTTT. IFTTT would create limitless possibilities including sending automated emails and text messages to your propane supplier for an automated refiling and automatically turning on the electric heater if you run out of propane...

  • The tank check is not worth it. period. fails to read the sensors. changing batteries and position doesn't help. one of the worst purchases I ever made.

  • Works as intended. Wish they had more tank types such as the ones you get from the home improvement stores. Standard sizes etc.
