I put that 3M film on all my accessible windows and doors. It takes 3-4 hits with a sledge to get through. Thieves don’t come prepaired for that and even if they are, the alarm would go off on the first hit. It’s also a very loud noise and an extra minute of smashing on a populated downtown street. Well worth the extra cost.
