It continually fails to back up files or create new folders. -- TRB!, 2024-10-02 ### ***** "What’s up with all the complaints???" Im going to have to agree with another comment that was posted.I don’t have any complaints about the drive it’s dependable the app for makes organization way better. I’m a software developer and I got to say kudos to the creator. -- Gensisitsolutions24, 2024-09-30 ### **--- "Not compatible" Worked great with older iphone. New phone with usb-c not compatible, even trying multiple lightening to usb-c converters -- Zzz do not buy, 2024-09-27 ### **--- "Needs lots of fixing" I only got this to free up space from all the pictures I take and it has completed that task but keeping the pictures it hasn’t it has corrupted photos and photos have turned up missing that were transferred glad they weren’t much important but still upsetting that this happened cuz they were helpful things to see and look at. Now that I know that this happens I’m just going to use this as a transfer tool if I find out it will work that way without deleting or destroying my photos. Would also be nice if I could just save apps to this device to have more storage for that but it doesn’t really work that way. -- Cheshire Katt, 2024-09-09 ### *---- "Keeps crashing all of a sudden" I don’t understand, I’ve transferred many files before and no issue, all of a sudden it’s not wanting to work. So disappointed -- KatieNight, 2024-08-17 ### *---- "Frustrated!!" I tried to download photos from my apple phone and the app keeps crashing or restarting itself. What a waist of time and money!!! -- Tweety4670, 2024-06-26 ### *---- "Crashes all the time" Not working. Crashes. It’s a shame that it’s not working -- aridejesus, 2024-05-08 ### *---- "Worst Set Up Possible" For anyone with the foresight to find out about this app before buying any PNY products relying on this app, clear as far away as possible. Not only are you forced to use this app (since the Duolink device I bought does not show up on the “Files” app), the app itself has the clunkiest, most unintuitive UI I’ve seen in a long while. From the looks of things, it isn’t getting updated anymore with anything worthwhile. The only thing that would make me change my opinion about this app and the duolink USB device is if an update allows it to show up in the standard iOS Files app on iPhone and iPad. -- Ubernova248, 2024-05-06 ### **--- "Not detecting that it is plugged into iphone!" Works fine on my pc but not detecting it is plugged into the iphone. It needs an software update! I’ve been using it just fine since I bought it, no issues until now. I need to transfer and it doesn’t detect it is plugged into my iphone. I have a iphone 7+. I will change my review to a 5 star when it is fixed.
