Very easy to assemble and align, rolls smoothly and wheels are well made. The posts that go through scupper holes will not work with lifetime kayaks unless you cut off the protective foam layer that these carts are assembled with. Once you cut that material off, the posts will easily slide into the scupper holes, but you'll want to be extra careful on bumpy terrain because without the material, they are a bit loose fitting and the bumping around could crack the hull at the scupper hole seams if you aren't careful.
