I believe this is the stuff some dealers charge multiple hundreds of dollars to install, in the form of a mandatory dealer add-on:

I'll save spectators a click. It's made by 3M and is 8 bucks. Of course, the dealers forcing customers to pay this probably aren't splurging on 3M at the outrageous price of $8 and are buying a knock-off brand in bulk, of course. Maybe $2? So we should probably assume it literally is close to 100% profit.
OP, I had a vehicle that had these installed by the dealer (I was not the original owner) and I never found them useful, but if you put them on for a few bucks and they make you worry less in parking lots then it's cheap peace of mind. I can't imagine the brand matters since they are basically strips of thick tape 🤣
These are just examples. I want to see what people have used and if they work :) .
