I like the concept of the plugr aerator and am interested in buying one but there is one problem. I call the # on the web site,I get a different # to call,then they say there will be someone getting in contact with me. Thats where it ends. Am I doing something wrong. I shouldn't have to jump through hoops for a company. I am sure parts would be a pain to get. Anybody else make a walk behind that won't beat the heck out of me. I like the cam driven system.
