The power tools are good but the box doesn't make too much sense to me and I have a hard time to put them back and lock it. Also, it's too high for my car and I can't really put it under my car unless I used rhino ramp to make a space. The lift force is very powerful, it can lift my tesla model 3 which weights 4000 lbs. It lifted without struggling by just plug in the power to the car 12V outlet. One thing can be improved is the auto stop, it won't stop going up or down until pushing the button. Though the machine won't really go over the limit and cause the problem but still better be careful. The outlook of the impact wrench is a little rough but it works. It can't adjust the level of torque but in the spec says 420 N.M which is pretty powerful and enough to unscrew the wheel nuts. Though I would recommend to screw the nuts in with a torque wrench and follow the spec on the car manual. My tesla model 3 spec is 175 N.M. and it won't be good with a high torque like 420 n.m.. Everything works fine for these sets of tools and very useful to carry in the car for emergency, not easy for a low profile car though.
