Counter experience, I recently asked Caroma ‘service’ what kind of grease is used in their soft close toilet seat hinges. Mine need a bit of TLC and it is a Very Simple mechanism, probably fixed up with a dab of ‘damping grease’ or whatever Caroma uses.
They refused to answer the question after multiple tries and gave me the part number to order new hinges ($60+).
After putting a few $1,000s Caroma’s way over a decade I am now putting Caroma products last on any list.
