FWIW, my wife didn't have any problems with her Welgo spd pedals in over 1000 miles of use. I recently upgraded her to the basic Shimano double sided spd as a gift. Functionally they were fine, but I'd be concerned that they would not hold up long term and I felt she would benefit from a double sided pedal.

Her only problems clipping in and out were related to screws backing out of her cleats. Just a little bit and it messes things up; once, she could not unclip and had to remove her shoe. You might want to check that first.

Regarding which pedals to buy: there is no right answer because different designs help specific issues. My wife uses spd for everything. I've used spd for casual riding and Speedplay lights for longer distance road use.

However, I just switched to Frogs for the casual/touring stuff because my right knee became aggravated when I exceeded ~25 miles on spd pedals. It was the right move for me because I had no issues in a recent 300 mile week long supported tour.
