Purchased this for deer lease truck, we often have to repair tires. after a couple of uses the flashlight ring just broke off. Sometimes you have to plug and unplug to get switch to finally engage the jack. Everything still works and I was impressed for what it will lift and the impact is kind of weak but it does what it needs to do for what I need. Overall what we paid and what it does it is not bad. I think it works good on flat ground but that is where you are supposed to use all jacks.
