The Canopener and the EZCan are two different systems, with different design uses, though some parts are similar. The EZCan is designed to be flexible and handle a large variety of different lights and functions. The Canopener is designed to work with Clearwater add-ons. The Canopener is not for sale separately, nor is it designed with flexibility of other companies products in mind. In other words, they do not compare very well.
