Just placed an order for this with the GEN3 Preprogramming and a windshield mount. I prefer the hardwired versus using bluetooth to an app like Hybrid Assistant. I will be able to constantly keep an eye on things versus dealing with my phone or tablet and Carista. You can find these at https://www.ultra-gauge.com
The main reason I didn't get one is because it doesn't have logging functionality. IMO all that goodness, id want to be able to stick a sd card into it so i can then take those logs to the data visualizer I built. Over time I have a notepad where i log the date, mileage and service done. In the end being able to see this or that made here or there differences in mpg and others. I ended up having a PCB board made that logs and can have a display added, but the kicker is it should work for techstream over bluetooth or wifi or at least be able to have a web gui versus an app for code clearing and the other good jazz hands. that lil screen is pretty adorable tho.
Finally it has been delivered and things look good so far. Will tinker around and set it up in the coming days and test things out.
