I don't want to write negative comments but I have a 16 Pro Max and it doesn't recognize it at all. I read the comments of a person here who says that we must first connect it to the computer, I have done that but still it doesn't read it. I have it in 256 + 512 GB, it doesn't read either of them.

While they say it works with the iPhone 15, unfortunately the phone doesn't recognize it at all. Basically wasted money. Unacceptable ... I didn't expect this from Sandick.

It works with iPhone 15 as well. However, what you need to do first for it to work is to connect it to an iPhone with a lightning port to update the firmware, and then it works normally with iPhone 15 with the usb c port

Extremely easy to use. It has the option for automatic backup of multimedia files as soon as it is connected to the iPhone, or alternatively, a manual selection of the ones we want. Very high-quality construction, noticeably better than other USB sticks. Ideally, it would have a slightly faster writing speed, but it may be limited by the phone in this matter

Very fast transfer to/from the iPhone 14 I have via lightning.
Fast transfer to/from the PC with USB-C.
I got the 64GB one for 30 euros. I consider it expensive, so I give it 4 stars instead of 5, but I had to make the purchase as it is the fastest solution to transfer 4000+ photos from PC to iPhone

Excellent product!
It does what it promises flawlessly.
4 stars because although it has a very good sturdy metal design/construction, the cover that protects the lighting can be completely removed and you can lose it at any time (even though it has a key slot, I don't think it is recommended)
