Ive had this device for about 2 weeks now, and it is mostly what I expected. It provides decent vehicle diagnostics, although they are very high-level stats. My car doesnt have any mechanical issues so I cant speak to the diagnostic/code reading features. My one big complaint, and its a big one, is that the Bluetooth does not automatically reconnect to my phone when I return to my vehicle. Sometimes I have to toggle the power on the speaker, but I usually have to "Forget This Device" on my iPhone 6SE and then go through the pairing process all over again. Even then, the speaker doesnt always pair with my phone. This is really annoying given that one of the main reasons I purchased the Hum is to add hands-free capability to my older vehicle.
Updated on 9/9: New app update. Now I cant even log in. I cant select the box to enter my email and password. So, its basically useless at this point.
