"Buyer Beware ! I purchased this SinkErator after doing a lot of research and even though it’s a decent product the rubber seal is too tight which causes water to sit in the sink and goes down very slowly . After contacting the seller 2 x I was told to contact the manufacturer instead of trying to help . Stay away from this seller , rude and unaccommodating ! Perfect example the price went up by almost $50.00 since I purchased less than 30 days ago !"
