I decided to buy the mounts despite the negative reviews I read. Assembly was a little time consuming due to height of my truck but worth the effort. I installed them on my Nissan Xterra to transport my bikes. The trip from Montréal Qc to Clearwater, FL and back went without any problems. Anyone who has concerns about the sturdiness of this product shouldn't. Driving through a tornado watch in Georgia and rain and high winds in Pennsylvania did even budge the bikes.
