When they work they are great!
I got these and instantly loved them...
but one of the springs cracked and it was such a pain to get look to replace them... you have to send the pedals to the retailer then they send them to look, then back to the retailer, then back to you....
You get the point, very long turn around for such a simple fix.
But that was a while ago. I've been using them for 6 months now and no problems at all... Like I said when they work they are great.
