$300 elliptical trainer machine. Its not that i didnt want to use it.. but the thing was so hard to put together... i had to call the help line... i told them ,... i can put together 20 different types of US navy underwater mines but was ready to throw this machine out the window. when i finally got it together it would "thump" every time i would step down. i didnt want to shake the ceiling on my downstairs neighbors and i only used it about 20 times before i threw it away (actually had a friend help me get it down 3 flights of stairs... i dont know what he did with it.
