PQI Air Pen‪+‬ 4+

Pen works quite fast but it's more of a photo & music player than anything else. You can't edit documents on the pen in this app or any other app, which I'd bought it for. You can only view files. You can't upload docs from other apps or import files from other iOS apps into it. Also you can only use a mini sd memory card in it, so you'd need a card adaptor if you were viewing files from a camera to it. You can transfer pics from your camera roll to it. I had hoped to work on docs from my laptop & then continue working on my ipad but it doesn't let you do it. Manual is difficult to understand & doesn't cover what you need. Would love to import from emails as email but can't see how. The description of what it can do is misleading, it should say it's more for photo storage & viewing. Also it only backs up to another pqi device that you have to buy with possibly the same limitations. With wifi it should allow to store to your own existing wifi storage devices

felt exited at the beginning, then i found out that the uploading from the mobile device to the pqi is badly designed.
1) the folder viewing to where u have to choose an uploading location is a small window making u scrolling twice as much
2) the folder viewing is in alphabetical order only, disregarding folder priority with no setting whats ever, ie: having 32gb of data the files management it get terribly lengthily/time consuming
3)when u upload, it only accesses to pics and video folder on ur iphone. But actually i need to upload PDFs, music, common file folders of other apps....
IT NEEDS:
1) upload (iphone to PQI) directly from anywhere while browsing files (from other apps and from the main file viewer i PQI software) without have to get into that tablet looking like icon in the PQI app
2) get access to internal iphone files in the same way as teamviewer

Glad I bought this bit of kit, allows me to back up my photos on the go and gaining that extra bit of storage for them tunes you don't want anyone seeing in your pay list,

After all I have read a few reviews and have noticed a few speaking about the limitation allowing them to connect to other devices, surely if you wanted to connect to your other Networked HDD surely they would have a server address that you could simply log on to
