we use to have that jack on all of our AAA trucks. the jack saw about 8-10 flats a day on our service trucks and 2-3 uses a day on the flatbeds. and they would last about 5-6 months then we would get a new one. awesome jack.
now the only reason they lasted such a short time was because we changed tires on f250’s on hills that were a 10% grade. not recommended. on flat uses and lighter duty i would buy the jack all day long. they are light and extremely durrable as long as you dont set the jack up sideways to how the car will roll.
