Query: Machine worked great for a while...

...but a part broke and I went to order a replacement part <which you can only get from the company directly> and it has been over three months. All they say is "sorry, it will ship some day". That is a big help. Worst customer service for a company I have ever dealt with. Great machine unless you need to deal with the company.Hope this helps.
