The InSinkErator Evolution Excel is part of the Garbage disposer
test program at Consumer Reports. In our lab tests, Garbage disposer
models like the Evolution Excel are rated on multiple criteria, such as those listed below.
Speed: We judged each model's speed of grinding beef bones and vegetable scraps. The speed of grind was based on the amount of bone that was ground in one minute of operation.
Fineness: We judged each model's fineness of grinding beef bones and vegetable scraps. The fineness of grind was based on the distribution of particle size after all bones were ground to completion.
Vegetable scraps: For vegetable scraps, whole celery stalks and whole potatoes were used.
HPModels with the least powerful, 1/2-hp motor can handle bones and softer waste such as carrots and corn kernels. But if your kitchen waste typically includes tougher stuff, look for a more powerful, 3/4-hp or 1-hp model.
WarrantyThe length of the warranty, in years.
