This product was very easy to use. Some tapes try to walk out of position, this one does not. I use a pressing cloth and then check to make sure the edges are well fused. It conforms nicely to the changes in thickness that the seams create. The only reason I gave it a 4 star not a 5, is I have not had the garment in use for a good length of time. Therefore, I cant vouch for longevity. So far, very good.
