My first pair of clipless pedals were M520s. I loosened the tightness bolt all the way to get used to them and just went up and down my block a few times to clip in and out. The pedal is fantastic and I have been using it to this day - 2500 miles later. I will say if you are doing heavy mountain bike cycling to give them a look over afterwards, as mud, clay, grime can build up. It's a great pedal at a cheap price.
