Review on FEOMOS Rain Glass Window Film - UV Blocking Removable Window Sticker - Static Cling Film Vinyl Decorative Glass Film for Windows and Doors - Privacy Non Adhesive Film - 23.6 x 78.7 inches by Laura Taylor

All in all a great product. Love the instructions, love the grid lines, easy to install and very forgiving. In my opinion if you want straight edges make sure you have a ruler OR cut 1/16" less on each side of your measurements and just adjust it to the window to fit. I didn't have a ruler (I used grid lines for the original size and it worked beautifully) and all my edges are jagged and it's driving me crazy.Uneven surfaces (remaining overlapping surface) cause it to shift and make it difficult to cut.Either way so user error not product error 5 stars and i will be ordering some for other areas in my house.
