Hi.I found no independent reviews about it. To me Winaso is as good as you will get.If you use the free or trial version it will only repair 10 items at a time but you can run it as often as you like.It does an automatic back up and has various other programs with it that you can use. Now I can recommend that.But unfortunately I have never tried Quad and the lack of recommendations would maybe put me off.
