This was impossible to apply. I followed the instructions. Immediately bits broke off when removing it from the backing sheet which was painstaking to attempt to remedy. Then to get it on the window this stuff is incredibly sticky. Any part of the film that touched the window stuck immediately and permanently. Again bits broke off and it was impossible to reposition. The result was an absolute mess. I have applied window film from a different company before with no issues. I contacted them and sent photos at their request asking for a refund but they have refused. Appalling. Expensive. Do not bother. Absolute rubbish.
