Nearly everything that came pre-installed from the factory on the "Motorized Retraction Slope Patio Awning" was backwards from the instructions provided. The install video also uses different higher quality parts (e.g blockers) than the cheap plastic parts that came with this product. It took my husband double the time to disassemble and uninstall the factory installed components and put them the right way as laid out in the instruction book. Also some of the metal parts came dented. Still in the process of installing because of the long drawn out process of correcting the shoddy factory pre-install that only made things more difficult; at least it's easy for us to not recommend Aleko to anyone unless you're someone who enjoys wasting your time.
