Review on 🪞 Haton Silver One Way Window Film Mirror Effect for Daytime Privacy, Heat Control, Anti-UV Sun Blocking, Adhesive Reflective Glass Cling Covering - Ideal for Home Office - Size 17.5 x 118 inches by Amanda Thibault

It's only one roll of film so you need a good razor blade, squeegee etc to make it look good. I ended up buying a small set and it worked very well. To be honest I applied it very randomly and didn't even clean the window beforehand, I've only lived somewhere for a few months and have a window on the main street and everything went fine. Lots of air bubbles from my own application but I didn't really bother them and left them at the end because they look almost decorative. The only downside is that it's impossible to cut a large roll that evenly. I have an old window with 20 individual panes, each 11" x 10". Cutting was a nightmare and I wish the back was solid and not transparent and had some sort of grid/lines on it to help with cutting out.
