BestDuplicator1 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!

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.

As Hams we are told repeatedly to backup the SD card in our pi-star hotspots. Too much work. Too busy. I’ll do it tomorrow. If you have dealt with a corrupt card you know what a PITA that is. This device is worth every penny.

Sent back a non working item and seller did not give a full refund. Scam!

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.

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.

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.

This really is a fairly straightforward plug and play device. The instructions are adequate (at least for copying… I’ve not tried the other functions), and it’s very easy to get up and running.It’s not a fast machine, but it does run at the speed promised in the documentation. So, I can’t fault it for performing 100% to spec. But, that is still probably my biggest issue. It’s fairly expensive for a simple operation, and you’d hope for maybe a little more horsepower to speed things up.But, all in all, it does everything I needed it to do, and it did it well!
