content: Fairly easy to put together....it has a magnetic safety clip that is not explained really well in the manual. Basically, it is a good feature because the machine will not operate unless you have the magnetic clip attached to the machine...thus preventing kids from being able to simply click the START button. In the same token, don't lose this clip or you cannot operate the machine. Also, please NOTE the ON button is hidden underneath the bottom front of the machine. Before you purchase, be sure to check that you have the right "power supply" for the machine so that you don't damage the machine or knock out your electricity in your home. Everytime you change "gears" (such as speed, program or turning the machine on or off, there is a really loud "beep"...so don't expect the baby to stay asleep while you work out....other than the above and in general we are happy with our purchase!
