    • Wonderful purchase
Color: Absinthe Green Size: 256 GB Style: Up to 400 MB/s
It works, My phone storage was 96 percent. I transferred some videos from my phone to the flash drive and freed up storage space to 70 percent. Will be transferring more stuff to it. The size is very small but convenient to carry around. The set up was easy and transfer was quick. It is reliable and will definitely be of great benefit. Price was good. I also like the fact that I can use the C part on my phone and the A part on my desktop. Definitely great purchase ... show more

    • Best performance , reliability and price. Works with any device
Color: Black Size: 256 GB Style: Up to 400 MB/s
Excellent Product for any device and was strategically purchased for Tesla car with dual port for iphone or android device to show to police officer right there on spot if tesla damages after incident and cant play video. Abosultely beast for Tesla cars and never dropped a single frame in the video due to lowest over heating buffer on USB stick is higher than output birthrate on all cameras writing at the same time. Highly recommend for iPhone, Android, ipad, android tablet or Tesla. Price is the best too for this class and nice data controller. Additionally, Amazon got 2 more stars to make it as 7 stars due that product arrived next day for 5-8 guaranteed for free. Love it a lot. It is smaller than on the image -smaller than half of the finger of the size. ... show more

    • Great buy
Color: Black Size: 128 GB Style: Up to 400 MB/s
This was well worth my money. I have so much on my phone that I wanted to save. So, when I brought my new phone, I could start brand new without losing any of my old pics and videos or without instantly maxing out my new phones memory. And I still have enough space to do it again when I get my next phone. I love how small it is. I can go on my key ring without adding bulk or weight. ... show more

Works as expected. So small, but large hole for the lanyard makes it easy to attach to key ring or my id holder.

Review Image by Mark A. Weiss
I bought this to use as a music source in my 2025 Mazda CX90. It was never reliable. I would get maybe one or two songs and then the audio would go silent and when I check my audio source in the menu, the USB device was offline. I'd have to unplug and replug it to get it back. Today, it isn't recognized at all. I even tried it in my phone. Not detected. When I plugged it into a Windows PC, it said there was a problem with this drive and could not repair it. So I am out the cost of this drive. Total waste of money. SanDisk used to be a trusted brand, but it looks like the quality control is nonexistent nowadays. ... show more

    • Almost perfect
Color: Black Size: 512 GB Style: Up to 400 MB/s
So far, I've been loving this drives speed and capacity. However, performance has been lacking as i noticed it disconnects rather frequently when used with my tablet and phone. Will updte when/if i find a fix but so far, Not deserving of a 5 star review. Update: Comparing this to other drives. It's slow. Annoyingly so. Writing to it literally takes about 2 minutes before even a small piece of the loading bar comes up. Even reading files takes a while. 🤦🏽♂️ Update 2: So I double checked the specs of my laptop just to make sure I'm not crazy. Confirmed the laptop has 2x USB Type C-3.2 Gen 1 ports and the drive is also USB Type C-3.2 Gen 1 and I have never seen this drive even get close to the advertised speeds. Extremely Disappointing! Update 3: I've found that the frequent disconnecting issue was a result of user error. Quick and to the point, Don't have your device in battery saver mode. I've had no issues with connectivity after finding this out. While the older 128gb sandisk pendrive i had didn't have the same issue this one has. I still prefer this as it doesnt get as hot as the older drive while having 4x the storage and slightly (albeit still slow) faster speeds. Worth it! ... show more

As I move data between devices and delete old, obsolete files, this drive has been a Godsend. It's so portable that I lost it in the pocket of my own backpack. It has been a reliable data partner for me. It has proven extremely easy to use, even for a tech-phobic friend whom I suggested buy one when he tried to convince me to do for him what he didn't think he could do for himself. ... show more

Great USB drive was hoping that I could charge my phone with this at the same time of using it but to bad so sad. Small easy to loose, put it down and if I cover it and push what ever I covered it with and not pay attention I have a hard time finding it. My desk is messy. It does feel like it can take some hat of a beating so it is pretty durable. Write and read speed is good although I haven't measured it so it functions good. I mainly use it to watch movies I have. ... show more
