I bought this online based on the advice of a friend and am very happy with the cart. It is very well built (better than the LL Bean pictures show) and fits my 2 kayaks (Necky Manitou Sport and Necky Manitou 14) very well.
It takes less than a minute to attach it to the yak. You can take the wheels off in 30 seconds by removing 2 pins and then the whole cart fits easily in any dry storage compartment on my kayaks. This cart beats many much more expensive ones and I highly recommend it.
