I had no problems assembling and installing this on the roof of my 2019 Subaru Crosstrek. The only thing I did that was totally my fault was I installed it and then realized I had to do the screws on the bottom of the crossbars to set the latch pieces in place so they don't move. All of the hardware is study and solid and the instructions were easy to follow. Make sure you do the little screws on the bottoms of the bars before you attach the bars to your side rails or you'll have to undo it all.
