Although I thought that it was hard to settle for a while, I used it for a while, but it became extremely difficult for the cab side to pull out and to fit in when it was winter. It takes time for daily maintenance. I will not buy it again.
Since I have used other products of the company, I understand about quality etc. but purchased but the perfection degree of the delivered product is too low. Although it may be cruel to compare with genuine products, the poor rubberiness and the accuracy of each part are loose. Since the size of the joint part with other parts is large and the adhesion degree is low, it absorbs unnecessary air. In addition, the inner diameter was obviously larger than the genuine product, and as a part of the intake system, it greatly affected the setting.
