When locating anything that's document related you can follow a "paper trail" so to
speak, check online, the government usually writes things like this down open to the
general public.
I always use Amazon to read reviews there are also many other websites such as Epinions. Alternatively you can just go to Google and type in 'Husqvarna Viking 3D reviews" and see what kind of results you get for your search. There are many websites online that collect product reviews.
