builders usually put in 1/2 hp disposals....we always spec one full hp and it does make a very noticeable difference in performance.

A couple of tips...small batches and always run plenty of water after the grind...let the disposer run with water into it for 15 plus seconds after the grind.

Just like you clean your toilet, you do have to clean the removeavle parts of a disposer. Especially the rubber flapper thingy in the opening. The better units have a removeable thingy. The others are permanent. And once you see the accumulation on the bottom of it one wonders what people do with the ones that do not remove. When it is out I also scrub the interior neck of the disposer with a bottle brush/old tooth brush.

No odors...no problems.

See my post #15 above. We never have any odors either, but you have to remember to clean that underside with soapy paper towels before running the sink full of soapy water through the disposal while it's running.

If you you follow the instructions on how to use your disposal, you will never have any problems. Yup, that's what that little book that comes with the disposal is for. :1rotfl:
Also a cleaning tip I use: put ice cubes in the disposal, then sprinkle in baking soda. Pour about a cup of vinegar in...slowly run water while running the disposal. This is a great way to clean and deodorize . The ice cubes actually sharpen the blades.

Use mine all the time - never had a problem - well, except once with those darned potato peels at Thanksgiving.
