The connection with the OBDC adapter is quite slow, at least as far as other Bluetooth devices i have in the house like external speakers. Takes about 5-10 seconds. The app seems to pull a lot of information, however there is absolutely no indication of any thresholds! I'd like to know if the numbers are within range or not, high, low, normal!? Guages are all red! Thats the last color i want to see!! Turns out its a design and you can change it, but again, no thresholds on the guages!

I would like to see an automatic connection to the adapter as well as a faster connection time, otherwise the features are on point and in-depth. I will also say with the PIDS this scanner allows you to see are far more in depth than other scanners of the Bluetooth type that I've used.

Works well. The setup of various displays is rather clunky, requiring maybe a dozen taps to resize then reposition each item. Also, it'd be great if the app would attempt to reconnect with the last adapter /vehicle when launched. So far (1+ years use) app periodically refuses to connect with adapter until I Uninstalled /reinstalled. Forget /re-find adapter doesn't work. Also updated firmware this recent time. Unknown if this fixed the issue. It DIDN'T. DAMMITT
