The package shipped on time. The packaging was manufactured original and secure, well protected product inside. Very happy with the package delivered. It's recommended having professional help for installation. But at the same time I suggest they can be installed by a novice with some technical training. The provided information/instructions are enough to get the shade tree mechanic through the install. We are very satisfied with the completed job. I have many years of technical training and while I was teaching during the install, we still took about 3 hours to get it done. Adjusting the beams does require pulling the assembly loose from the mounts in order to access the adjusting bolt heads. I have added 3 photos of our 2007 Pontiac G5 GT, finished install. Needless to say made a great improvement to safer night travels. Well worth the cost.
