    Abstract: Some example product dispensers that accommodate two full paper towel rolls are provided herein. The product dispenser may employ separate dispensing mechanisms for each product roll and may include roll holders that articulate out from the housing to facilitate easy loading and access to replacement and loading of the other product roll. A roll partition may be utilized to separate the web paths of the two product rolls and enable rotation of front roll holders. Example funnel covers and nip covers can aid with intuitive installation. Example roll holders with retention mechanisms help prevent unintentional dropping of the installed product roll. Other beneficial features include utilizing motor operation sensing to dispense a desired sheet length, automatic/assisted loading into the dispensing mechanism, automatic switching between dispensing of product rolls, and always dispensing from the smaller product roll first. Many other features/structures of example product dispensers are also described herein.
