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!

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.

Works exactly as expected. You need to only push 1 button to duplicate two cards at a time. I knocked it off 1 star because 2 of the 3 SD card adapters were broken upon receipt. I had plenty so it wasn’t worth returning, but was a little disappointing to have broken items.

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.

I tried to copy pictures from a 128 G SD phone card, to a 1T SD phone card for a new phones external card slot. Got about 80G in and the Red error light came on. After lots of digging, there is information that says different SD card sizes may...cause errors in copying. Not May.. it WILL, cause an error. Not only was the job incomplete, but the pictures were not recognized, and the SD card capacity was reduced by 90%. Luckily a reformat via the phones software restored the storage, (and wiped the drive). But, "best duplicator" is now a $150 doorstop.

worth the price and just a little time consuming with copying

This worked perfectly. It takes a few seconds to copy an SD card and does it from either portable or desk top.very happy with purchase

I purchased this to make a backup copy of an SD card that drives one of our components. While the device DID make a copy (the setting was set to Complete Copy/Compare - Whole Media) the copy did not work. All indicators showed the copy completed successfully but the new card did not work in the device. Very disappointing. This must have some limited capabilities not disclosed in the information.
