The method of identifying the true and false of vents

Direct hands-on inspection: From the surface, there will be some obvious pressure points on both sides of the vents. From this basic feature, you can know whether the purchased vents are genuine. Therefore, in order to avoid buying fake vents, you must learn how to identify them before buying, and it is possible to use the correct method to identify them reasonably. Therefore, a simple detection based on the pressure points on both sides is sufficient.
