Review on Shimano SPD Mountain Bike Bicycle Sealed Clipless Pedals - Venzo Dual Function Platform Multi-Use Compatible - Touring, Road, Trekking Bikes by Jim Kriegshauser

I attempted to install these on Shimano crank arms. Tried to start the left one and it wouldn’t work. I learned early in life to start EVERY threaded part by hand, otherwise the threads get stripped (never a good outcome).Sending them back. Frustrated because they were the last part I needed to upgrade my wife’s bike.Follow-up—It was a quality control problem. ebay sent a replacement set that work very well.
