This has not worked well for me. It is not clear in the description, but it doesn't work well with Android devices, only IoS/Apple. It does not have the capability of presenting text files in pdf or docx formats, which is what I mostly wanted it for (without using a computer). I find the controls hard to use, there appears to be no provision to change the slide show interval from a rather short five seconds, there is no way to advance to the next photo in slide show mode without calling up a menu which hides 1/3rd of the screen (a button on the remote would be nicer). etc etc. I'm sure this is a lovely machine for watching movies but it doesn't work for me, where I want to give presentations of mixed materials without a computer or wifi connection.
