Product review (4 stars): Works fine as a cheap replacement unit.
Bought this to replace a bad Kenmore unit at my Mom's house.

It's tiny because it doesn't have the added plastic shell around it to "bulk it up" but it seems to be just as powerful as any other 1/2HP units available in the big box stores for twice the price.  It's no louder than any standard Badger unit, though possibly a tiny bit quieter.

Install was a breeze-- ended up taking me more time figuring out how to remove the Kenmore mounting bracket than to re-install the new unit. Trick for those having trouble: rotate the disposal into the locking ring until it catches first instead of trying to hold the unit still and manipulating the ring. Once it's "hanging" it can easily be turned into position then tightened.  If you're needing some excessive amount of force to "push it into the gasket" tight enough as some have described you're doing something wrong, or your gasket is installed incorrectly. (It pushes up until it seats in a grove on the drain.)

This unit has a built-in power cord, which is usually a plus. It can be a minor nuisance if you have a hard-wired disposal as it cannot simply be removed.  I ended up just mounting an outlet under the sink using the existing power and plugging it in... a $5 fix that took an extra 20 minutes.

The drain also threw me for a few minutes.  Our previous Kenmore install used a straight pipe out of the disposal instead of the L that came with this one.  This disposal uses an odd gasket that slips on to the lip of the pipe.  Apparently it just pulls off and slips around the lip of any standard piping. I just needed to pull it off and wrap it around the end of my old straight connector and that sealed just fine.

If this had a hex-drive on the bottom for breaking loose jams it would be a perfect 5 star disposal.  When even the instruction sheet suggests using a broomstick wedged down your drain to bust a jam I frown a bit. This is a very minor gripe.

Overall a great low-priced replacement... big savings over the availability at the big box hardware stores, and available in 2 days thanks to Prime.  Very happy with this purchase.
