The advertising says HIGH QUALITY but in my opinion they are any thing but. The installation instructions are not very complete and tell you to install parts after you have it completely together so you have to take it back apart to install the support roller the model I purchased is 20 foot long and one support roller is not sufficient and was told that by one of the sales reps the ends of the support arms started cracking and splitting apart and the one support roller broke on the first attempt at extending the awning out I contacted aleko and they would not warranty the part because they couldn't verify if it was factory defective or improper install well if you read the manual it only goes on one way and it was installed correctly so I had to buy a replacement roller support and I purchased a second roller support because one isn't enough to support the 20 foot tube. The materials used are cheap and weak and will break if you try to adjust any part of the awning. I WOULD NOT RECOMMEND THIS AWNING TO ANYONE.
