The functionality of the M5350 is very high. Alone the built-in display already has a lot of information, such as network coverage, registered WLAN clients and upload / download volume. In the settings that can be accessed via the browser of the computer, almost all adjustments can be made, which can also be expected at home on a router for DSL line. Unfortunately, there is no separate app (at least not for Android), with the hotspot can be controlled. This can face competition from Huawei much better. Also the equipment in use is very hot, so you hate to wear it in the summer in your pocket. But in winter it is therefore likely to have a great hand warmer. Worst of all, but I find the housing quality. The housing can be already not as described open at the notch, but only using the fingernails with laborious hand over hand at the slots of the back cover. Very sad, I also find that the built-in MicroSD slot can not be controlled via WiFi to exchange data with other example. So the Hotspot funkiert only when connected via USB as "USB stick". Therefore, the unit goes back, I'll buy the Huawei E5331 and can only awarded 3 stars here.
