When I want to buy another card reader it won't be a SanDisk.
I shall look at Kingston and Lexar when I want to buy another card reader.
I forgot to contact my card company despite costing less than £100.
I think that the total invoice or receipt must cost at least £100 although paying just £1 on a credit card for it (part payment) and the rest of £99 paid on the credit card if paid for other things would be valid to get the full cost of the card reader refunded from the credit card company.
24th July 2015 I purchased one, I thought that since the SD card in my Win 10 PC only had an SD < = 4 GB because of the format SDHC < = 32 GB and SDXC < = 2TB was probably created after I got the multi-slot inserted into my tailor made PC as an optional extra.
Sandisk eventually admitted to me that it definitely won't work for CF Cards but since I was using it for a 32 GB MicroSDHC Card it wouldn't be a problem but I did have problems.
Eventually, SanDisk in Europe responsible for the UK sent me a cheap USB 2.0 Reader from the USA. I complained about a refund but they refused. - I have hardly used it, I connect the SanDisk 64 GB OTG (on the go) into one of my Window 10 PC's USB slot to transfer data from Moto G 3rd Gen, 2015, model No: XT1541 Android Smartphone. - Don't have much faith in their After Sales Customer Support. - Problem is that in 2015 there wasn't much choice.
My problem was internally faulty connection inside the Micro SDHC socket which was also verified even by professional photographers whom some had purchased SanDisk products for years claimed and SanDisk ignored them also they claimed. - Explain why the company was sold probably to Western Digital Company: reminds me of people rushing to leave the sinking ship before it sinks.
