Hello. I purchased this Arrow Carport through Shelter Logic for my son and I must say we were extremely impressed with this Carport. First of all , it arrived 2 days early . A little ify on the tracking , but it got here very quickly (3 Days ) and it was secured on quality skids . 
Once we opened the 3 boxes it came in and began assembling this carport , I was really impressed with the carport , but also the packaging and hardware. This unit is so well designed it is a no brainer why they offer a 10 year warranty. Took my son and I , 8 hrs to assemble and the finishing details like 3 rolls of sealer for the roof panels , edging for the front and rear edges of the roof , every self taping screw had a rubber seal ( we had plenty of screws to assemble this entire unit ) and amazing achors to secure the entire structure . This is by far the best carport I have ever seen comming from an on line purchase. Absolutely a 5 star rating.
