Since college over 10 years ago, I’ve loved Precor’s elliptical lines. I finally decided to purchase a personal one for my home garage. After 3 uses, I couldn’t be happier. There was a slight squeak on the roller/rail but Precor sent a maintenance guy and he put a bit of mineral oil & emphasized dusting the machine daily helps. He also said it’s normal and no grease or other lubricants are necessary (as YouTube was suggesting). The sound went away! 10/10. I’m sure I’ll buy a better one in 15 years once this one runs it’s course. But this one is super solid for starters! For reference I’m 5’11 220 lbs
