CHECKBOOK provides subscriber comments on their experiences with the firms they use. Please remember that individual subscriber comments are informal. Subscriber comments may give you insight into the types of features and problems that exist in a service field, but are not the best basis for selecting or rejecting a specific firm. To assess the quality of a firm's performance, we recommend that you give more weight to the percentages of favorable ratings. Those percentages are generally based on much larger numbers of consumers' ratings (the number of consumer ratings is noted above).
