Ratings and reviews

An app that never connects to its own devices nor does it have any useful or redeeming qualities. They sell you on it being able to show you live E85 readings, but the app hasn't done that since the first month...

I bought my Proflex second hand. I saw the app ratings and my expectations were very low. However, the app does work, it shows the ethanol content, I had to reload the app initially to show the E85 content but the app does its job so far.

Opening the app is fine. Once turning the key on to see how much ethinol I have in my car pressed on the device after a little bit the app couldn't connect. Was so disappointed. I hope this is just a glitch.
