Question: What about staff members who reported problems for the product "rem"?
SQL: SELECT T3.staff_first_name ,  T3.staff_last_name FROM problems AS T1 JOIN product AS T2 JOIN staff AS T3 ON T1.product_id  =  T2.product_id AND T1.reported_by_staff_id  =  T3.staff_id WHERE T2.product_name  =  "rem"
