I give it a 9 because of one shortcoming for me, the seat. At 5'9" and 160 lbs. my bony butt hurts after 2-3 hours. Don't have this problem in other brands. The addition of a YakPad solved the problem. I recommend this kayak.
All parts fit together as they should, I didn't have to force anything. The trailer tracks perfectly straight and does not bounce loaded or unloaded. The handle is now included in the basic package. The only thing I can say that is less than complimentary is that I had to splice in a piece of wire to make the ground wire long enough and the tail light wiring connections were a bit of a problem until I figured out that I could take the red lens off to gain access to the connectors.
I highly recommend this product.
