I recently needed a hidden zipper to be replaced in a pair of slacks. I tried doing it myself first and didn't like how I did it so I took them in to the "professionals". I thought they would do a better job than I did. Boy was I wrong. It took them over a week to get them done. When I went into pick them up, the top of the pants was not even at the top of the zipper. One side was noticeably higher. I had done a better job my self. I will not use them again. I had called around for price comparisons. This place was a little cheaper than others in the area. However, after seeing their work, it was not worth the savings. The zipper does work but I have to keep a top over the top of them so that you don't see the zipper. Don't make the same mistake!
