Query: Great for losing wieght, horrible noise after 1 month

I am giving this machine 2 stars because although it works -- I lost 10 pounds in a month by using it 3-4 times a week for 15-30 mins -- after 1 month of usage, the machine makes horrible noise. It is so loud, you cannot bear it, and if you turn the TV on to silence it, you can't even hear the TV! I used to use it late at night but now I can't because it wakes up my kids. I wish the part responsible for this was of better quality so that I could enjoy my machine much longer.
