Too slow, somewhat confusing App

Actually I think the idea of ​​a wireless hotspot for mobile disk Super, unfortunately hurts the MLW221 here put to many. For example, the use as a power bank is only conditionally recommended since the storage capacity of the battery but is very low compared to modern smartphones and tablets, and is therefore at best be described as a sheet-anchor.
The app looks simple and it is. It lacks many configuration options that we know from our own wireless router. Navigating and selecting the right file's hard because here even something like a "Created on" missing view. You can see the files while after "date" sort, but we are not told when they were created precisely because this information is missing.
The data transfer is tiring slowly, images from the SD card of my Sony RX100 (20MP o. 3-5MB per image) takes per image about 2-3sec.

This I have unfortunately seen better, unfortunately failed the "EasyAcc portable 4in1 Wifi Wireless" on the processing, after just over a year broke the WLAN module.

I will search for a device that meets my needs, this is an interim solution to the price quite ok.
