These are some of the features that make this product to be rated among one of the best garbage disposal units available in this range. Let us look at some of them.

Power Cord Attachment

All waste king garbage disposal units usually come with their own power cable. This is always advantageous because, without the cable, you will be forced to look for some other alternatives of connecting your garbage disposal to the power supply. The only alternative we both know though is hard wiring. With hard wiring, you can always experience all sorts of electrical problems when you do it incorrectly. This usually causes the unit to stop working and many people always don’t seem to figure out why it stopped working. This unit coming with its own power cable, it reduces the chances of electrical faults. Besides, it also saves you like $10 because you won’t have to buy it.

Noise level

As we have seen above on the features of the waste king legend 9940, we said it has a sound insulating shell which prevents it from producing much noise when in use. This is so true, even when operating a ¾ horsepower motor; you will always have a quiet environment to work in. On other waste king products, like the waste king legend 3200, they have rubber dampers which reduce the noise and vibration even further. From the reviews, you will notice that many people actually switched from the other garbage disposal products to use the waste king 9940 or 3200. For those using the InSinkErator Badger series, you will realize that they do have weaker motors and no insulation which makes them be very noisy when being used. This makes the waste king 9940 the best upgrade for an affordable price.

Grinding power

As we have seen, those using the InSinkErator will always complain about the weaker motors than the waste king 9940. This is something that made a lot of customers shift from using the InSinkErators to the waste king 9940 when doing their upgrades. With this, they were impressed to realize they now had the freedom to grind many types of food waste. With a motor speed of 2700 rpm, you can grind almost anything from carrots to small animal bones. Besides, the grinding is always continuous.


The waste king legend 9940 has both the two mounting systems. These are the EZ mount system and the 3 bolt mount system. However, the installation is usually done only once so you will have to go with the type of installation that will serve you for a long period of time. The waste king legend 9940 is always durable but the decision for which type of installation to use lies with you. Just whatever method you choose to use as this is a matter of your own preference.


  • It has an affordable price

Value for money Waste King is available for a little over $100 and that makes it an extremely reasonably priced device.
