I got me the Huawei E5331 bought to be on the move to rely on any hotspots with iPad / laptop to the Internet can not. Positive is the speed between the devices. You notice virtually no difference to the normal WLAN. Is also sufficient power is going too fast browsing of equip. The battery pack is such a thing. I "travel" between Duisburg and Dusseldorf back and forth and am here about an hour always on the go. As long usually keeps even the battery. The exchange of radio masts is likely then something too much for the small modem. If you stay in one place and has neat Emfang makes Huawei but also good daily (~ 9h) with in my surfing habits. Since each another surfing behavior creates the day can look at other people also markedly different. SSID and Key are in the cover for the battery and also under the battery. I find this very handy if you the sticker inside the cover, why should always lose time also. A disadvantage, however, has the Huawei my opinion: It is fucking hot (which in turn means that as useless energy is wasted, do not worry you do not burn your fingers to it). I think here is a design fault, you would the battery would then be given more effort keep you safe longer. Bottom line, the unit but worth every penny.
