The steering wheel booster ball was originally designed for buses, trucks, and buses, which have a lot of steering wheel turns. It can save effort to make a lap, but now many people buy it for small passenger car owners. In order to be lazy to save a little effort when turning, U-turning, and reversing, but it is practical to use this booster ball to operate the steering wheel with one hand, especially in emergency situations, which is extremely dangerous. kind of center console shading mat was something I wanted to buy at the beginning. It doesn\u2019t matter whether it\u2019s shading or not, it mainly makes the car look clean and car light. But in fact, if it is fully enclosed from time to time, it will cover the airbag originally designed in the co-pilot position, which will undoubtedly cause danger to the co-pilot passengers in the event of a collision.
