It wasn't clear to me from the description if this was a "hopping" foot (what is needed for FMQ). However, reading the reviews showed that it does indeed have a spring and someone used it to quilt a baby quilt. You do have to be careful because sometimes a piecing foot is sold as a quilting foot. This, however, appears to be the right kind of foot for FMQ.
One good thing about buying from Amazon's in-stock stuff (not 3rd party sellers) is that returns are very easy.
