InSinkErator Evolution Compact vs Frigidaire 1/2 HP Corded

Overall Verdict

The InSinkErator Evolution Compact is quite bulky for a 3/4 HP machine. The Frigidaire, on the other hand, is much slimmer, but what really matters is performance. The Frigidaire only proved effective in grinding down mixed scarps. It was unable to manage any waste with either bones or soft cartilage.

The InSinkErator Evolution Compact, however, is an excellent all-round disposal and with a fairly spacious grind chamber. If the Frigidaire suits your needs it does cost less than half the price. However, there are better garbage disposals for its class and range, such as the Amazon Commercial 3/4 HP.
