Purchased on Nexus 5 and a Note 3, nothing to say for 18 months. The installation is simple but better follow the tutorials in video on YouTube to understand before embarking. Protection is impeccable, keys, falls, nothing was damaged. The color rendering is just perfect, full transparency. I'll stay on that brand. Only default the glass gently craquele on down, I'll have to buy one, but after 18 months, it is honest.
