BBB Customer Review Rating plus BBB Rating is not a guarantee of a business' reliability or performance, and BBB recommends that consumers consider a business' BBB Rating and Customer Review Rating in addition to all other available information about the business. If the BBB Rating is NR then only Customer Reviews are used for the Star Rating.
