Was delivered ahead of estimated time !! 5stars to Wayfair !! However, the Bi-fold doors look great out of the box but immediately noticed folding the doors prior to installation was difficult and binding badly due to hinges were mounted out of alignment. After careful realignment, mounting, movement was nice, smooth and looked great. After opening and closing door several times we noticed white flakes falling from upper track area. We found the inner track edges were very sharp and actually cutting into the cheap plastic upper track guide pins !! I've decided to replace all the guide-pins with a different material myself but.. Although I'll continue buying from Wayfair (great online store),, , I would Never buy again or recommend anyone buy this brand of doors !!
