Some individuals take pride in owning the best of the best. They want the highest end products that deliver on promises and become the envy of neighbors everywhere. InSinkErator is known for making high-end garbage disposal units, but their best product hands-down is the Evolution Excel 1.0 HP Food Waste Disposer.

Quiet, energy efficient, and most importantly effective, the high power motor disintegrates food waste in literally seconds. If you want to include the best garbage disposal unit on your list of the “best of the best”, then you will need to check out the Evolution Excel.

Motor Power & Performance

The InSinkErator Evolution Excel has a powerful 1 Horsepower Dura-Drive Induction motor along with 3 grind stages that allows for more efficient usage. This product combines a GrindShear Ring, Tri-Action Lug system, and Undercutter Disk, along with a Jam-Sensor circuit that automatically increases torque to break through jams with ease. No need to worry about clogs or drainage issues since the grinding stages pulverize food waste into the tiniest particles possible.

Feed Type

This model has continuous-feed operation which makes it easy and convenient to use. Simply flip on the switch to turn it on and start pushing the food waste into the unit until you have disposed of everything. It then flows through your pipes and sewer to your local water treatment plant where they can harness the methane gas into a renewable resource used to power the plant. That’s a great way to decrease your carbon footprint and increase your green-living.

Materials & Components

The main chamber and grinding components of the ISE Evolution Excel are constructed of stainless steel to ensure it will not breakdown due to rust or corrosion. Since the Evolution series by InSinkErator is top-of-the-line when it comes to food waste disposers, you can expect durability and a long lifespan when you purchase any of the Evolution series garbage disposals.


When you think of a garbage disposal, you often think of a very loud and obnoxious machine. Fortunately, the ISE Evolution Excel 1.0 is designed with SoundSeal Technology Plus which makes this unit 60% quieter than standard garbage disposals.

InSinkErator’s SoundSeal technology utilizes components such as Anti-Vibration Mount, Anti-Vibration Tailpipe Mount, and Quiet Collar Sink Baffle along with SoundLimiter insulation so you will even be able to hold a normal conversation level when the unit is on.


If you consider yourself a DIY-er and like to tackle installation of kitchen appliances on your own, you’ll be thankful for the ISE Evolution Excel. It features a Quick-Lock sink mount that will allow you to disconnect your old unit and replace it with the new unit without any extra effort or parts needed.

If your current model is not hardwired, but instead plugged in to an under sink power outlet, you can purchase an extra power cord kit separately that will alleviate the need to hardwire the Evolution Excel. Simply plug and go!

Dimensions & Capacity

The ISE Evolution Excel 1.0 HP garbage disposal is 13 ½ inches and 25.5 pounds. More impressively though is the grind chamber capacity which is one of the largest in its class. It holds up to 40 ounces of food waste at a time, so you’ll have no problems quickly disposing of a large amount of leftover food all at once.

The Evolution Excel also is one of the quietest garbage disposals on the market. People are astounded at how quiet it is and often comment on how they sometimes wonder if it’s even on since it’s so ridiculously quiet. This is great for large families or households with little children as the product will not disturb everyone in the house, or neighborhood, with a loud, obnoxious grinding noise like most standard models.

The look of the Evolution Excel has also made a great impression on many customers. It has a stainless steel body and many customers commented that it looks “beautiful” which is a great benefit for people who plan to resell their house.


While most people had glowing reviews, a few have experienced some problems with the Evolution Excel unit. These include missing parts, leaking, and incompatibility with current sink and fixtures. Overall these do seem to be isolated incidences and not a common occurrence.

The biggest problem customers face with InSinkErator is their customer service. When individuals made a phone call to have a problem fixed or to contact customer service, they were diverted to a call center in the Philippians which did not bode well with customers. The representatives had issues understanding basic questions and didn’t provide much help. This can pose an issue for people who expect a high level of good customer service from companies that they buy from.

Consumer Reviews

The InSinkErator Evolution Excel scored almost perfectly when all of the reviews and ratings were combined. Over 90% of people gave the ISE Evolution Excel a perfect score of 5 out of 5. That’s a pretty good percentage; enough to have confidence in the company, the product, and the design and durability.
