BestDuplicator SD300 1:2 Portable SD/microSD Card Duplicator

I was looking for an easy way to duplicate Raspberry Pi images and this works perfectly for that purpose. I'm able to easily backup and create exact copies of my many Pi OS images. I didn't see a lot of other options out there and what I did find was way more expensive so this was exactly what I was looking for. You will not be disappointed. I normally don't write reviews but like I said, there were not a lot of other options, so I felt compelled to let other people in my situation know how happy I am with this purchase. 5 stars all the way!

We were on our way to install a bunch of Raspberry Pi's. I created a single image and my son was in the car duplicating cards as we drove. Being battery powered is great. Being portable is great!!! Make sure you wait for the success message as once we stopped thinking it was done and had to redo those 2 drives. Once it says done (and you'll only make that mistake once), its very reliable.

Worked good for a couple months. Then any micro sd-card placed in slot 2 would heat up until it melted the sd-card carrier. The micro sd-card was hot enough to the touch that it couldn’t be handled until it cooled down. Can’t recommend using this copier.

I really like this copier. It does copy everything, system files and all. It has some nice utilities such as r/w speed, this was a bonus for me since it identified some bad disks. The instructions are good to ok, The only drawback I ran into is, it will not copy to a slightly undersized disk. The menus seem fine to me. Pretty intuitive. Also need to realize the Source spot is limited in function - as intended. Overall a great product.

Made maintaining my play against order much less stressful. I always have an identical clone I can fall back on as I adapt and all I have to do it plug it in. The Raspberry Pi Ubuntu Ethernet DMA overruns would have been much more aggravating with my safe clone to fall back on.

So this does exactly what it is supposed to well, although it would be nice to have a website for support. The SD card adapters are defective as previous posts mention. The micro SD card does not slide in easy, so it seems you're breaking something forcing the card in. I did find a manufacturer website that was similar to this product, and there I found that the device copies the FAT table from the source, which means if you're trying to move data to a larger SD card it will mean your device will not be able to access any storage beyond the size of the source SD card. That doesn't work for me. The copy is definitely quicker than doing it on a PC, but I have to return this product.
