I am now in the 4th generation owner of Huawei. Always very happy so far with the price / performance ratio. I currently own the Y 201 for quite some time. For me, absolutely sufficient. My wife still has a predecessor, the Ideos X3. This I had earlier also, well not anymore. Ergo is for you something new into the house clear of Huawei. And again what really great, the G510. Wonderfully part, big and beautiful .... if the WLAN is at all possible to activate. We are at home 5 persons, each with a smartphone, of course. All have Wi-Fi reception problems (Sony, Samsung and Huawei). With this device, we have all failed. Even the fast supplied replacement unit has brought no Internet connection status. The disappointment in size, the consequence is Sony. Hopefully it gets better ....
