best floor jack guide

A jack is a device that uses force to lift heavy loads. The primary mechanism with which force is applied varies, depending on the specific type of jack, but is typically a screw thread or a hydraulic cylinder. Jacks can be categorized based on the type of force they employ: mechanical or hydraulic. I wanted to buy a jack for my car maintenance but the one which are available in the market were really confusing. So I am currently looking for one in the internet according to the best floor jack guide.
