This is NO different than the cheap Chinese "knock-offs" you find on Amazon. It even says "Made in China" on the box.
The slide hammer is to small ande using a hammer method to remove poses unnecessary risks opposed to pull systems.
Also the lip that grabs on to the bearing is to small so it rounds easy. The solution would be to tighten the nut more to grab the bearing harder but the manual says to not do that because the fragile material they choose will break.
This is not an item made to make your life easier and last a lifetime, its a cash grab product from Motion Pro. Avoid it.
