Mike wrote a review of Shimano PD-M530 MTB SPD Pedals on September 5, 2012
These were my first clipless pedals after many years of platforms and clips. They work just fine and I got my confidence in them built up pretty quick. I really had no issues with them until I bought a used bike that had XTR M980 pedals on it. The XTRs work smoother and easier, but its the difference between a $30 pedal made in China or Taiwan and a $170-$270 (depending on where you buy) pedal made in Japan. I think the performance of the M530 is pretty good for someone looking to try their first clipless pedal or for a clipless pedal on a budget.
