BestDuplicator - 1 to 2 Target SD/MicroSD 1:2 Copy Portable Flash 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!

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.

I love my micro sd card duplicator one of the best thing that I have order on amazon thank you amazon the price was just right.you don't have use the computer the flash copy tester sd 300 Duplicator copy much faster and you don't have to worry about getting that virus on your computer all you to do is put the micro sd in and copy it's so easy the prices for you can't beat it ,it's really great you would really love this , I Used to look for someone to made copy for me and pay for them now I don't have I have my on duplicate sd

This did not work for me. It came in a 300+ box with 300+ documentation. When it didn't work as expected I was told by customer support that it was defective. The replacement came in the same box, same documentation and didn't work for me either so I sent that back as well.

Too much experimentaton and too little manual. Works great when you first format your targets sd or sd micro card using the utilities menu step and then backing out of utilites and find the copy or copy and compare menu. Slot one is the master, slots 2 and 3 are the slot towhere to clone the master. works from bigger to smaller sd micro card when the master data is less then the size of the target sd or sd micro card.

Returned because it was unable to duplicate an SD card (could have been because it was encrypted - but it should have still been able to transfer the data regardless).

This little box does the magic of copying SD card without using computer. All you need to do is to put the original SD card in the left slot and put a new SD card in the next slot and use the arrow button to show "copy" In the window. And then push the button with the ⭕ on it and the little box will start to copy your SD card. As simple as that! Wonderful gadget for people value their original data so you always have a copy on hand.
