I’ve had this device for about a year which is used for my short term vacation rental in Lake Havasu, AZ. It’s worked well until last month when it stopped reading. Changed the lithium batteries as a precaution and it did not correct the problem. I emailed their support and they indicated they would replace my unit but they were out of stock with no indication of when it would be back in stock. But like most of these reviews indicate the device is fairly reliable and decently built, however the app is terrible. For example, I use the device to monitor the gallons used for 2-7 days at a time by my guests. It is extremely difficult sometimes to review a particular day when my only choice is to press on the graph. It can take a minute or more for the app to recognize the day I want to look at because there is no way to zoom in on one day so it reads temperature, the day before or day after instead. Maybe it’s my fat fingers but if I could zoom in my fingers would be able to click the correct day. Maybe have an option to show a “list” format for daily gallons used as well as the graph so I don’t waste my time messing with the app for so long.The app overall seems like there was no thought put into it. Get with a developer and make it user friendly with some forethought.

Bought the newest version in November, and after a month it’s still working good. I did have to set it up twice due to changing WiFi routers. We have had plenty of rain and the unit still functions normally. App does need improvement though. The ability to receive real time readings is essential. At the least it should have a “check level” button instead of having to wait for the once a day reading. I understand that battery life is what drives the once a day readings. Perhaps making it easier to change batteries, or better yet, a solar panel to keep it powered would be the improvement the unit needs. The idea is great but still needs improving to make it a 5 star unit. I will update my review if anything changes.

I’ve been using this product for 12+ months now and I have to say - this is one rock solid product - no questions asked! I live on the mid-coast of Maine (Downeast) and can attest to this unit being subjected to many sub-freezing days - rain - sleet - snow - ice - you get the picture... Most recently a tropical storm that wiped power out for 5 days. The unit and app didn’t skip a beat. Once the standby generator restored power and our internet re-connected - I was monitoring the fuel usage while on generator power remotely. One less thing to worry about when you’re told “trees are down everywhere!” Good news is no injuries and no damage. So... I just used the “Order” option for the first time. Waiting to see how that goes as I am down 150 gallons unexpectedly. Stuff like this always messes up our auto delivery. Since I’ve never used this option until now - I expect my “gas company” will be getting in touch with me to confirm the delivery. More later on that experience... All in all - this product has given me ZERO issues. I’d give it 6 (six) stars easily! Bob, Downeast

I have two propane tanks with a utility device on each, 320 and 500 gals respectively. Each device has performed for a year with no issues. The app, however, suddenly began acting erratically. Both tanks were showing as the same tank, with all the same info, and the capacity shown for both had reverted to 50 gals. The app would not allow me to edit either tank's capacity to restore the correct number of gallons per tank. I kept correcting the capacity on each in the Edit mode and clicking " Save" but this changed nothing. Closed the app, reopened, each tank still showed 50 gallons capacity.I then deleted both tanks from the app and re-added them with all the correct info, which was a pain. After doing so, the 320 gal tank reverted to 500 gals. I edited it back to 320. I closed the app, reopened it... and both tanks' capacity had reverted to 50 gals, again, and both tanks had duplicate info as well. I deleted the app, then reinstalled it.Same story-- wrong info, wrong gallons, unable to save any editing, even if I only entered one tank. In the latter case all the info was correctly saved except the gallonage again kept reverting to 50 gals.In short, the app has a bug. I'll have to call my supplier and see if they can straighten it out somehow. Meanwhile, not happy with this app.
