When it comes to scissor jacks, people always think that they are the most cost-effective among all car jacks, and the reason given is relatively simple, that is, the price of scissor jacks is much cheaper than most car jacks. So is this statement correct?

First of all, we need to clarify that cheap price does not necessarily mean high cost-effectiveness, and there are also situations where cheap price has low cost-effectiveness. We need to clarify what cost-effectiveness means. Cost effectiveness is the ratio of a product's performance value to its price value, which is a quantitative measurement of its affordability. The full name of cost-effectiveness is performance price ratio, which is a proportional relationship between performance and price. The specific formula is: cost-effectiveness=performance/price.

The cost-effectiveness should be based on your requirements for product performance, that is to say, meeting the performance requirements first, and then discussing whether the price is appropriate. Through this, it should be clear that the use environment of scissor jacks is still limited. Generally, scissor jacks cannot be used in complex and harsh terrain environments. If they are used in such environments for a long time, then even if scissor jacks are cheap, they cannot be considered cost-effective.
