I didn't even know such a thing existed at first. I am torn between novelty, functionality and practicality. this jack. It gets five stars for novelty and functionality. I couldn't help but play with the jack like it was a grown up version of a remote control car. It's just cool. In terms of functionality it's great too, the kit is well designed, it contains what makes a complete emergency kit, some of the stand out items are: - an electric jack with a remote controlled impact wrench - an adapter you can connect to a cigarette lighter socket or directly to the battery to power an impact wrench or electric jack - Velcro sleeve on the outside to keep it from moving around in the trunk. A few thoughtful things like a warning triangular reflector on the carry case and an emergency glass hammer, things I wasn't expecting. Now for practicality, I'm not entirely sure I'll be taking this with me as it takes up extra space compared to the factory one. If I had a bigger car/truck I would definitely consider it, you are giving up storage anyway so you need to take stock of what is more important to you. Solid 5 stars for value for money. . The buyer must decide if space is an acceptable compromise to achieve this value. If you found this review helpful, I would appreciate it if you could click 'helpful', thanks!
