There are many consumer satisfaction tests available, see for a somewhat dated but informative review Westbrook & Oliver (1981). Most often, simple, single-item rating scales are employed. Reportedly, there is little uniformity in the number of scale steps used and in the anchoring. They often range from 3-point labeled rating scales (e.g.., good - neutral - bad) to 10- and 11-point variants labeled only at the extremes and midpoint (e.g., 0= bad; 5 = neutral; 10= excellent).
An interesting consumer questionnaire I found was devised by Lou et al. (2007). It was devised for assessing people's satisfaction with drinking water and consisted of a general part I with personal information (Fig. 1), and a part II specifically testing consumer satisfaction (Fig. 2). Because the authors targeted specifically the defining characteristics of drinking water based on the Water Taste and Odor Wheel you might want to adapt certain questions in part II to match your specific needs.
