Bests & Worsts Reviews from Amazon

Like the other reviewer I replaced an older one with this. The trick is that older garbage disposals tend to have something called a three-point attachment just under the sink, while newer ones like this have a new design that rotates on. Now if you want to replace the current part that's in the sink this doesn't matter. But then you need the plumber's putty like the other reviewer said (unless it's a stainless steel sink, whose smooth surface apparently doesn't leak). On the other hand you can do what I did and buy an adapter. This mounted under the sink, allowing me to keep the part you see in the sink when you look down, and thereby obviating the need for applying plumber's putty. It cost about $15 at Orchard Supply, but I'm sure you can get one from Amazon. It bolted to the sink part easily, and the Waste King rotated onto the adapter equally easily. The only problem was that the adapter lowered the garbage disposal itself half an inch or so. I wound up going to Home Depot and rummaging around in their disordered bins until I found the pieces of piping I needed. It was a snap to install them once I got home, though. Plastic piping has become so standard, and works so well, it's hard to remember the old days when you needed plumber's putty for everything. Now the installation under the sink looks professional, I've upgraded from a 1/3 to a 1/2 hp. motor, it's quieter (and mostly plastic, as the other reviewer said). This came with a 5 year warranty, and if I'd bought a more expensive Waste King I could have gotten a one-owner lifetime warranty. But this seemed good enough. And it was a much longer warranty than the comparable Kenmore unit. It also came with a power cord built in. Didn't have to wire up anything. I'd say, in general, that plumbing has become much easier for do-it-yourselfers. So if you're hesitating, I recommend going for it.
