I had my ODC for 1 year. The only defective thing I ran into was the oars. I bent one while fishin' the Russian River for steelhead this past winter.
I did some damage of my own to it while driving home from Clear Lake. I didn't tie it down well enough and it took a beating when it flew out.

I got the River Runner. Here's a URL to check it out. http://www.waterskeeter.com/ws_river_runner.htm
In my opinion it's much better than the ODC. Particularly when it comes to speed. Which reminds me, the blades on the ODC oars are way smaller than the blades on the River Runner. Which could be why the River Runner is so much faster.
If you get an ODC, buy different oars.
