I’m pretty impressed with the jack and impact driver. I think the jack could be improved upon with just a couple changes. Firstly, the switch to operate the jack would be considerably safer were it to be a momentary switch. People get distracted and if they move away while jacking, and the jack continues to operate, they could potentially injure themselves or cause damage to their vehicle. Secondly, perhaps think about adding a pair of extendable side braces. I was forced to use the jack on a slightly angled surface and learned my lesson to pay attention. The jack was almost at its height limit and I was preparing to put the jack stand under the vehicle when the jack rolled sideways and dropped the car. Thankfully I was not yet under it.
This is just my input. Because, again, I’m quite impressed with it.
