new $47 petsmart xp3 has BLACK rotating wheel inside the external casing on the underside of the top disconnect where the goo-like sealant is(when you secure the handle it rotates and secures the disconnect to the top lid) well it wasnt seating like it should and when securing a *snap* showed me one side of the black securing wheel broke. it now is seating properly and is easy enough to secure, it doesnt look like it should be a problem because it looks like it should when the handle is secured down.(have not tried it yet)..Anyone else experience this? thank you.
