I’m gonna go ahead and give this machine a 5 star rating even though I had to make a trip to the hardware store for some missing nuts and bolts. Once assembled it worked great. It pulls smooth as long as after assembly, you put some oil on the column that the weights move along. I’ve been using it multiple times per week without any issues for a few weeks now. It doesn’t seem unstable or likely to tip like some of the other reviewers have said, but then again, I’m only using it as intended (pull downs, rows, tricep extensions, cable curls etc.). I’m 5’9” and get full extension on lat pull downs, with the seat at the lowest position, with about two inches before the weights bottom out. If you’re taller than 6’ you may be better off going with a different machine, otherwise it’s a great buy for the price.
