Customers find the memory card reader fast at transferring large video files and praise its functionality, build quality, and ease of use. Moreover, they appreciate its simple design and consider it good value for money. However, the device lacks a USB-C port, and several customers note that the included USB cable is too short.

Much faster read speeds thanks to USB-C vs. USB 3.0 - Great if you have high-speed memory cards!

- Reviewed in the United States on February 1, 2023I needed to replace my CF Card reader, I decided to go with the SanDisk ImageMate. What attracted to me was the SanDisk brand and the over all design of the reader. It is well built, deceptively heavy for its compact design, and is easily packed into my camera bag. The USB cable that included is not very long but it is detachable and can be replaced with a longer cable.
I have been using it regularly for the past month and it works well, I have not measured the transfer rate but transfers go through a good rate. I would recommend this if you are looking for a memory card reader.
- Reviewed in the United States on April 21, 2022Love it. I've tried three other readers and found this one the only one to hit the max read speeds according to the SD cards ratings. Previous card readers no matter if they were usb 2 or 3, plugged into usb 2,3,3.1 ports never copied files faster than 45Mb/s. This reader his 125Mb/s on the slower cards and on the high perf 225Mb/s.
50 minutes vs 10 minutes to copy off a SD card allows me to shave a hour or two after a photo shoot and reduces the possibility of an outside interruption to the process (windows updates, backups, family). If you get distracted like I do the speed reduces the chances of forgetting what stage of my process I'm at.
Two previous card readers would overheat and stop working, often corrupting files or worse the card itself. This reader handles multiple cards easily without overheating. As for the card corruption, solved the problem by formatting the sd card in camera before reusing the card for important events. No more transfer issues.
Worth the money, especially if you've invested in fast cards and ssd drives.
- Reviewed in the United States on June 11, 2024If you want accurate speed readings on SD cards, then your reader and cable need to be adequate. This reader works. I was skeptical of the performance of a card I recently bought and was questioning its authenticity. This proved it was an old, outdated reader. The card was good. Performance of this is fast. Expensive compared to budget readers for obvious reasons.
- Reviewed in the United States on February 9, 2025This is the real deal. I finally bought this after buying so many nonsense no name brand CF readers again and again off Amazon that kept corrupting photos during transfer or failing outright within the first month or two. There is a lot of garbage on the market. This is not one of them.
- Reviewed in the United States on March 16, 2021Works great, fast read write speed, stays connected, no drivers needed. I’ve used all 3 cards ports. Remember certain cards have their own transfer speed restrictions, I see a big difference in newer higher rated SD for my hero 7 vs the cards I use in my hero 3.
The micro sd is spring loaded, the regular sd and cf are manual pull out.
The cord could be longer as I’m using this with a desktop PC but for my laptop it would be perfect. Although it connects usb-c to the computer, it does use the wider USB connector on the device itself, which is less likely to be laying around if you wanted to change the cord cheap or easily.
Overall I’d purchase again and am happy with this reader!

5.0 out of 5 stars A Good value, fast reader, with an odd cable choice
Using this with a SanDisk Extreme Pro 1 TB microSDXC card gave me a write speed of 100 MByte/sec and a Read speed of 140MB/s - 10 times quicker than my old Sandisk Reader.
The reader feels solidly built, the SD Slots have a latch mechanism to stop accidental disconnects, and there's a nice "In use" Light on the top of the device - it's a nice palmable size, too.
It's also very well priced for the build quality and speed.
The only drawback is that it's not a true USB-C Device: On the back of the unit is a MicroUSB3 socket, and in the box a MicroUSB3 to USB-C Cable - MicroUSB3 is a bit of an unusual connector, so while they give you everything you need in the box, it limits the "Use Everywhere" appeal as you have to carry a rare-ish cable around with you.
I'm using mine with a PIHEN USB 3.0 A to Micro B Cable (https://www.amazon.co.uk/gp/product/B075M62PXB), as my photo rig has USB3, but not USB-C. Also have a PIHEN USB-C to Micro B Cable to use as a high quality travel cable (https://www.amazon.co.uk/gp/product/B07JDYDQH6)

5.0 out of 5 stars Perfect Card reader - Really good product!
This is a good card reader and a very reliable one. The advantage is that it come with a Micro B cable on the card-reader end for Data + Power supply, which is usually used for portable hard drives and USB-C on the device end such at Mac Pc. And I can actually use my portable hard drives Micro B to USB 3.0 for Windows pc. The card reader is heavy which is on a good side because its a durable and sturdy built.
