The Badger 1 may be the number one seller in the country due to price point. Works OK if you don't overload it. 1 Year warranty, life expectancy 3 to 6 years. Badger 5 nice step up, 2 year warr. life 4 to 8 years. Both are noisy. The Evolution series is well worth the extra money......all are very quiet, and have more SS parts, hence longer life.
