Reviewers are quick to point out an interesting fact about U.S. freezers: They're all primarily manufactured by three companies, Frigidaire, W.C. Woods (based in Canada) and Haier. Frigidaire brands include Frigidaire, Gibson, Kenmore, and General Electric freezers, among others. W.C. Woods brands include Amana, Magic Chef, Maytag, Danby and Whirlpool. Haier makes smaller freezers for GE, Kenmore and Amana in addition to selling some models under its own name. Thus, it's no surprise that reviewers find no significant differences in efficiency and performance between brands of the same manufacturers (as long as they're new models of similar size and style). This also means that shoppers often pay a premium for high-profile names when the products are nearly identical. For example, Frigidaire freezers sometimes cost more than General Electric models and Maytag units may fetch a premium over Whirlpools.
