Smallish Chinese manufacturer, no international presence, their phones are nothing really special. Internal storage only 4GB total, so if you like installing many apps, you'll have problems. If you get any problems, you'll be sending it back to Shenzhen on your own dime. How good is your Mandarin? Also if you're in North America, be aware that they might not have the appropriate LTE and 3G bands. Very likely no Google. Software updates for bug fixes or latest Android versions, non-existent or good luck really.
