This is a very well engineered and manufactured product! The parts fit exactly as intended and was very easy to assemble. The ease of assembly for transporting the yak is good and very quick. I towed my fully loaded fishing kayak 2.5 miles each way, 4 days in a row and it towed very well. I kept the speeds to 15 mph or less and it tracked straight and didn't bounce or get squirrely.
My only two changes would be: 1. Make the axle bar a little heavier so the tires don't make it float. I like the trailer to stay put when I'm loading the yak back on! 2. Instead of using spring clips in the tongue bar connection, I'm going to use a heavy duty clevis pin since gettig the spring clips depressed far enough to release and get those two sections apart is quite a challenge.
