after purchasing my cub cadet 40in and mowed lawn had 2flats, after looked online for something to find to keep tires from going flat or replacing them found tireject n could not believe reviews, but since I added tireject have not had any flats or low tires on my cub cadet. After 2 yrs added again recommended n now going on 4 yrs without a flat tire or having to replace a tire. I have 6 big lots that I mow during the spring and summer. Definitely recommend add to tires.
Does nothing the website doesn't already do. Anything good that an app could be for (like reminders for when to reapply) is just a form to get an email reminder. The app serves no purpose.
