    At first I thought that the scratched display came, opened the dispute, it turned out to be a protective film (never would have guessed) because neither of the hooks anything and it is deeply glued, as if the screen. The store sent a video of how to shoot it, and the truth, the film. The device is cool, the colors are juicy, beautiful. QC 3.0 supports, checked. Thank you. Seller recommend. I advise you to write about what is on the screen film.

    It came in a month. 5 stars I will not put, so as not to mislead the interested. But, given the cost, as a toy-quite so. I will not advise either, for the express test (Works/does not work)-suitable, for more/less accurate measurements-absolutely no.
