Frameless universal wiper U3 is same as U-shaped windshield wiper T3, they have same appearance, same material, the difference is that U3 is much stronger than T3 theoretically speaking, as T3 only made of plastic cover, although the plastic cover is strong enough, U3 have an zinc-allong in the plastic cover, soU3 is stronger than T3 theoretically speaking. Actually T3 is strong enough, the products have tested in many markets by many many cars, but if you want to make it 100% strong enough then you could choose U3.For front windscreen wiper, when we are driving quickly, there will be a big wind resistance to the windshield wipers, even we are not in high speed, The friction between the wiper and the windshield glass can also generate huge torque, the wiper blade should have a strong spring steel and middle part( as we refered the plastic and zinc-alloy in the middle). If the spring steel is strong enough, the result is that the wiper blade deforms when moving on the windshield, if the middle part is not strong enough, the result is the cover in the middle crack and the windshield wiper fly away. You imagine how dangerous it is if you are in a heavy rain and you are driving in high speed, the windshield wiper fly away suddenly, if you like pls contact with us, we will share with you some of the videos about the dangerous situations.
