I installed by myself today. It is hard to mount -I had to prop it up in place inorder to turn locking ring. Very heavy to hold by self and turn or even with two people. Neother of which worked. Propping it up in place worked great. I used an inverted tea pitcher. Plastic casing tends to turn while installing, but easily fixed.

Very strong, chopped up watermelon rind and old dried out hamberger patty. Does not have a key to unlock (just incase), but features a reset buttong instead which is suppose to do the same thing. My old had a key and only used twice in 10 years, so may never be an issue. 2 stage grinder should prevent pipe clogs that I had happen a few times in my old model. Removable splash gaurd in nice feature.

Much quieter than my previous insinkerator badger 5. I saw the reivews about being noisy, but compared to my previous one (and my mothers) it is much quieter. I don't expect silence when considering it intended job. For only 1 day use it has been great.
