I installed it myself, which generated my only complaint.... I'm a 130 lb woman, and this thing is heavy and very difficult to get it into place inside the cabinet under the sink. I looked all over for other comments and solutions to this problem but never could find any. So I just kept adding books/magazines underneath it to jack it up into the correct height! Finally, LOL, it was high enough for me to lock it into place. The product works great and is very very quiet.
