My son likes the Note 3 Pro mobile phone
Advantages: I purchased mobile phone for my son. We both were positively surprised that Google Play store app was already installed on the phone. So we easily could start downloading Google apps like Whatsapp from the Google app store. Moreover we liked that MIUI 8 supports GERMAN language. The phone I think has a very good performance to price ratio. Which was the reason why I tried to convince my son to purchase the phone. He has saved some cash and wanted to spend 200,-Euros. Luckily he did purchase the HUAWEI P9 lite but purchased instead the Xiaomi Note 3 pro from Gearbest.
Limitations: To early to tell. Not supporting the 800MHz LTE band is at least not an advantage if you use the phone in GERMANY. Many telephone companies use that LTE band over here, especially in rural areas. But it is not that big of an issue. At least not if considering the item price. Moreover, if you take into account that not all applications do need to be supported by LTE.
