I was very impressed with the build quality of this slider, especially considering the affordable price. It slides super smooth. I do feel like my friction slider may be a little easier to get consistently smooth shots with just because it doesn't slide quite so easily. Roller sliders slide so effortlessly that it can be tough to keep a consistent speed. With that said I'm still very happy with the quality of this particular slider and have liked everything I've gotten from Flexsmart so far.
