ZARMST Flash Drive for iPhone 256GB, 4 in 1 USB Type C Memory Stick, Photo Stick External Storage Thumb Drive for iPhone iPad Android Computer, Sky Blue

I am highly impressed by the quality of this product. Spacious device. User friendly.

Does the job that was expected to do for both I Phone and Android

Works very well with my iphone. If you're looking for a usb to free up space this is a good choice. While there are cheaper options out there, they often compromise on build quality or compatibility. Worth it if you want peace of mind and consistent performance. Easy to use. Happy with my purchase.

The flash drive didn't require any formatting to use on my iPhone 16 Pro Max. The user manual qA already visible on the drive. A couple of clicks, the app was downloaded from Apple's App Store, a brief read through the manual, and I was able to copy off photos, including DNG files, satisfactorily. I plugged the drive into my computer's USB port and the photos were easily copied to a hard drive. Note that by default some files are renamed as PNG files instead of DNG. The manual describes the app setting to copy the image files unchanged. The drive didn't overheat. Yes. the DNG files were large so transfer to my PC was not instant. The drive has some flimsy feeling plastic, so I was care to avoid forcing it into the Type A slot on my PC. But the drive worked quite well overall. and was inexpensive. Five stars.

Not too good never got it to work
