Works correctly if you use as intended or prep the area.
For those who post pictures of the system failing it is due to not mounting it in a masonry wall as described in the instructions. I placed a sheet of plywood on the wall and mounted to that and the rack nicely holds all of our bikes.
Really made a lot of room in my garage. Comes in two pieces so you have some flexibility with where to I stall them. One rack holds all four of my adult sized family bikes.
