Ben M.wrote a review of Harmony Sit-On-Top Cart on March 25, 2015
Familiarity: I've used it several times
Pretty simple; not a lot to review - adjustable arms that fit perfectly through the scupper holes on my Jackson Cuda12. Once secured, it rolls perfectly - no issues whatsoever. My only issue is that the strap secures to the cam buckle _under_ the boat, leaving you with a bunch of extra webbinig to secure to the top of the boat; in and of itself, no big deal, but a rubber-coated bucklesecured to the unit with a couple of feet of webbing so that you could tighten it on the side, rather than below, would have been perfect. Minor design flaw in an otherwise perfect unit. Highly recommended for sit on tops.
Oh, and FWIW, this was an exchange for a Sea-To-Summit kayak cart which definitely did *not* work with the Cuda12. I was talking to the person who initiated the exchange and asked for some different color goat stickers in the box with the Harmony. The Harmony arrived with no stickers. The stickers arrived a couple of days later in a stamped envelope - now that's awesome follow-up. With everything we all have going on to remember to send some stickers out is the perfect blend of the personal touch when doing business over the Internet. Bridges the gap between local and the cloud. Well done, BC.
