Not worth it. Get another brand.
I bought the F2 model and the fingerprint scanner didn't last a month. I tried to reach customer support but they never replied. I had problems with the mic, somehow it fixed itself before customer support could reply (they didn't). Bluetooth pairing is weird, 4.0 version is supposed to handle up to 8 devices at a time and whenever i link more than two, they start to randomly disconnect. I chipped the back glass and now the touchscreen is working weird but i don't have any hope they will help me with it. It sucks because the phone itself isn't bad, battery life is great and although is a heavy phone (over 400grs if i'm correct) it works good. It should be better than this, but yet it falls short at most areas that actually matter.
