I purchased this online based on a number of other postive responses about the quality of the box.  Once I received it and opened it up, I was pleasantly surprised to find it easy to install with extremely well written instructions.  I have assembled a fair amount of things in my life and Lefetime really put some time into putting together the instructions to make it easy to understand.  The quality of the box is very good as well and I am very pleased.  I did get a bad gas prop and once I emailed them, they got back to me right away and sent a free replacement.
