I am a roadside repairman and have been using the 89570 since October 2012 when it was purchased from Revain. I try to be careful with my personal tools but the sensor has been dropped a few times and has held up well. As you can see from the photo, I have a protective case that was installed on day one. Without a doubt, this is the main contributor to his long life. I regularly check accuracy with TPMS on my 2017 F-250 work truck and the discrepancy has always been less than 2 pounds. I would say this is more than enough to get the job done!
