The tool was well packaged with a nice pouch for future storage. Batteries are not included, so you need to order two CR2032 batteries in advance. Once I had them, it took me about two minutes to put in the batteries, download the app, and pair the devices. what to do. An important point to note is the switching bus (LF, RF, RR, LR in that order) and the power change input type. If you want to measure the tread depth again, simply reset it to 0 and measure again. I liked the ability to enter Vin and get standards. Measurements were quickly captured in the application. Submitting the results required a little more effort. I have successfully sent a screenshot of the first car to myself (PNG file emailed). However, it took me a little longer to find the page to submit the results - the tire setup page. I personally haven't used this feature yet, so it didn't really matter. While working on the second car I had to remember to clean up the result of the previous car. Overall, I found it easy to get up and running. No training is required to know if a car's tires are in good condition. I rate it 4/5 because the application can use some simplifications in the export methods and perhaps a clear understanding of the workflow (what to do first, second etc.). I received this product for free in exchange for an honest review.
