Query: Very bad;

These are not like normal windshield wipers. For some reason, the design requires that you insert an unusual piece into the wiper. I tried to follow the instructions, but it did not make sense. In turn, the wipers would not fit on my car.I promptly went to an auto parts store and bought another set (that has the normal connections) and popped it on in 10 seconds.Do yourself a favor and buy another brand (unless, of course, you're an auto repair specialist and can read crude illustrations).
