Use of Miami's Roommate Match Tool?

Does anyone know if students tend to be happy with roommates chosen through Miami’s roommate match tool? It seems good from the standpoint that you could choose a non-smoker (if desired) and could possibly find a roommate who keeps the same sleep hours (i.e. 10 pm to 6 am or 12 midnight to 9 am, etc.)
Any thoughts would be most appreciated!

My daughter had a roommate through the match but she ended up not attending in the fall. Random roommate was assigned about two weeks in. Completely fine and they are still friends.
