I have had on of these for a year and have used it for a 200 mile self contained tour and many grocery and shopping runs. I find that if I get over about 35 lbs the handling of the bike is effected quite a bit. I use a rear triangle mount kickstand from greenfield and it works just fine. When I used the center mount stand it didn't work well at all. I originally had an issue with the ball bearing in the quick release mechanism, the hole in the think was not round and the bearing would fall out. Nashbar gave me a new one and I haven't had any more problems. I have found it to be useful and did I mention cheap.
