I put it on a road bike and put it on about 200 miles on medium smooth/rough country roads. Hit a few potholes every now and then. No issues with the stem squeaking/popping and it seems perfectly solid to me. The only caveat is that the handlebar grip is a bit flimsy, so I had to use a rubber washer to hold it in place without over-tightening the clamp bolts. Edit: The rubber gasket wasn't good enough. I ended up using spray glue to really fix it in place.
