Square 2Nd Generation Bluetooth Le Mobile Card Reader

I use these in my Canon 5D Mk3 and Mk4. The price point for SD cards is much better than CF's, and now that speeds are up there, this is a no-brainer 2nd slot backup. The cards I use are 170MB/s 64GB SanDisk Extreme Pro's, and there's never any lag. Also worth noting that I can ditch the big, multislot card reader, and carry a small SD card reader for porting shots to my MacBook. Highly recommended. Important note: this is the 2nd adapter I've tried (B&H was great about the return) - I don't use WiFi SD's, so I thought that was unimportant and went with the cheaper model also from DigiGear, but it didn't fit in either of my cameras. Don't be tempted - that other model is almost twice as thick, and will not fit the 5D Mk3 or 4...

This keyboard is perfect as a mobile or a 2nd keyboard.

Read the fine print. This uses Bluetooth LE, and that requires an iPad3 or better. After wondering why it didn't work with either iPad2 here, I found that tidbit (which I had missed) in the fine print, hemmed, hawed, and opted to upgrade the iPad side of the system. It is a quality product, which on the one hand seems quite pricey for what is effectively a 2 button bluetooth keyboard, but on the other hand is much better made than whatever I might kludge up from a cheaper bluetooth keyboard with many more keys. The keys are lit, soft, and silent, and the device is considerably more affordable than some others in its niche - and with the keys on top, not over the edge, it works fine on carpets (some reviews indicate that is a weakness of some competing devices.) For hands-free page turning it really is ideal. Intended for foot operation, it is a bit larger than you'd expect from the pictures.

The OTG card reader is a plus!

Works well, only wish it would come with the appropriate card reader.

A very fast card reader!

This is the best choice for a card reader.

Great card reader.

Great when I am Mobile, and I love the Bluetooth capability.

I purchased this SanDisk Professional PRO-READER Multi Card Reader after my laptop SD card reader failed. Ordered it from B&H overnight delivery and it arrived at 10am next day - so kudos to B&H for that. Here's my first thoughts on this SanDisk card reader: -It's fast! First time using it was able download 202 21MP photos from Import to ready to edit in the Develop module in Lightroom in 40 seconds - about 1/4 of the time required compared to my laptop's now defunct card reader. Your milage will vary. -It's USB-C 3.2 version 2 as advertised. (My Windows 11 ProArt Studio laptop does have a USB-C 4 Thunderbolt input. However Thunderbolt card readers cost $200-$300 or more, which was more than I was willing to pay, so this SanDisk reader was a happy compromise. Nevertheless, plugged it into the Thunderbolt port to attain the download speed I mentioned above). -Build quality. The case is made of rugged ribbed aluminum that I think will stand up exceptionally well in a busy office environment. It also looks 'professional' as it not constructed of cheap looking plastic. On the bottom of the case there are four small rubber feet that should stop it from sliding around on a desk like plastic card readers are wont to do. Finally, and this is a big plus for this Sandisk card reader compared to another plasticky 'Top Seller' sold for the same price, the several times I have use it so far it never became too hot to touch or to remove the SD card from it. It's one cool dude, in fact. - Size wise, it's roughly the size of a business card though maybe an inch longer. And if you require more than one I believe SanDisk offers a raid style enclosure to accommodate up to four. My conclusion: This SanDisk Professional PRO-READER Multi Card Reader is very fast, well built, looks professional and stays cool to the touch. So, would I recommend it to a friend. Absolutely!
