I am a huge fan of the Normatec legs. As such, I purchased the full body set. I use the legs almost on a daily basis. The hip attachment is great, but I don't use it as frequently. The arm attachments are very hard to use when by yourself. It's almost impossible to get them on, snug, and then start and stop the machine. Overall I am highly satisfied with my purchase, but knocked it down 1 star due to the arm attachments. I really wish you could use multiple attachments at once.
