I've had them on my MTB commuter 8 years. Love them! Convenient and quiet when closed. I keep two canvas shopping bags in my "trunk" to line the baskets so small items don't escape, and a small bunge in each to secure bags. Here's my bike from last week or so. I had an additional backpack and laptop to take to work and the baskets made it easy. +1 position the baskets back to avoid heel strikes.
