I bought this for my LZ602 Shark mainly because my dog somehow removed the original and chewed on the most important part. This replacement worked for a few weeks but has not been fixed now. Compared to the new one, it seems to be made of ABS plastic (black) and the original one has some kind of gray resin. I can say that it is much stronger and harder. So I didn't really save any money with the purchase and ordered directly from the Shars parts page. Luckily I was able to sign up for an email and save 10% but now I've paid more than I should have. One of Shark snapped very hard and has a mate other than this one.
