Kriko reads a listing and tells you which of these apply to that exact product. It runs on your computer, needs no account and is free.
These reports come from the pages linked under each item: owner forums, repair guides and workshops. They are not a diagnosis of any one unit, and a careful check of the one you are buying still applies.
