The cart worked well on a recent trip where I needed it to get to the water without driving, about a 15-minute haul on foot each way, each time. I may put in a very thin foam pad or shelf-liner to make softer contact between the "scoop" and the hull. But in stock form, it holds the kayak well (with straps).
It can be easily disassembled without tools. I can put the wheels inside not only my 10" bow or stern hatch openings, but even inside my smaller day hatch, with room to spare.
I have not yet checked whether the plastic hull "scoop" holder will fit inside my hatches if detached from the rest of the cart (it won't go inside there with only the wheels removed). But if it does not, the assembly minus the wheels can go in front of my footpegs. Actually the entire cart fits in there but I'm not wild about putting something in there that could cause entrapment.
I await a reduced-size version of the very solid C-Tug to be produced (or something like it). In the meantime, this little device works surprisingly well on hard surfaces, and it packs down quite small.
