So far so good. The Zerk fitting is not a self-tapping screw, which is nice. The design is similar to the shop brand but with some differences which may be an advantage, time will tell how it will last. A private label usually lasts between 6 months and 1 year. There are no problems with their installation. So far, I barely notice the power steering assistance compared to the store's trademark. The steering gear was also replaced. Bye. I would be happy about that.
