U-Reach Data Solutions SD300 Best Duplicator Portable 1:2 SD/Micro SD Flash Duplicator

This is a great device for backing up SD and mini SD cards, say while travelling. I want to use it on safaris so the fact it can operate on batteries is an advantage. It is very easy to use for that purpose but the accompanying manual is poor and confuses the operator. Since almost all customers would buy this to make straightforward card backups, the manual should begin with a page saying this:1. If you want to make a data backup, load batteries or use the power adapter. Turn on the power switch at the side2. Put the source SD card in slot 1 and the destination card in slot 2. Another destination card can be put in slot 3 if required.3. Use formatted cards of the same data size for source and destination.4. Press the button marked 05. When the device has scanned your cards, press button 0 again and the data will be copied.6. When the display shows that the process is finished it will also report whether the destination card is OK.7. For all other purposes, e.g. if you have cards of different capacity and need to use the asynchronous copy method or you need to format the card, erase the card, or do a bit by bit copy of the entire card, consult the relevant manual section. We also recommend you read the whole manual before using the product - just in case!
