It has trouble connecting or staying connected but works well when it does. The map that shows other user readings is horrible. They haven't updated that in years. The map is peppered with old data and its no fun to view at all. They seriously need to do something with it. I have to sort of wonder how accurate it is if the app is so sloppy then why would I assume the hardware is accurate?

I totally don't understand the ratings given by most of these people. Admittedly most are over a year old, and the app may have been improved since then, but it worked perfectly for me on the first try with an Android phone that is not even on Bactrack's approved list. Maybe that means all of the bugs have been worked out. Love it, and my new Mobile Pro reads exactly the same as my old standby, the Pro 80, which I bought several years ago because it the police standard.

honestly the accuracy has been pretty good but it doesn't stay attached to a device I have to wait several times and restart it before Bluetooth will recognize it the feature I want it for with for the graph afterwards and every single time and I mean that every single time crashes when I try to look at the graph. I really wanted to like this but I'm starting to think I might need to return it since cannot even see your results without .the the app installed.since the app doesnt work....useless
