Like a little glass that breaks, it did its job perfectly. Luckily, I had bought it because even though I have another phone for GPS, which is older, I had put this one once. It was unfortunate because it fell between the driver's seat and the gearshift on the iron base of the seat. The little glass cracked, but the phone didn't suffer any damage. I had bought it a little more expensive than the minimum price, but it doesn't matter. It cost me 7-8 euros instead of the 330 that the phone was worth when I bought it.

P.S. In a previous phone, I had put a thinner membrane in a similar case, but then the phone broke and the membrane remained stuck on the screen!! The result was that as soon as the membrane came off, the phone started to open in a thousand pieces. It may make the phone grow by 3 millimeters, which is a bit annoying, but if you want protection, I think it's the only thing that does the job. What can the membrane do, really? Has anyone saved their phone with a membrane? Not me
