I purchased and imported to Australia three of these card readers for the purpose of ingesting data from 6 ProGrade SD Cards simultaneously onto my video editing workstation's NVME drive. I'm very pleased that the transfer rate is so high even whilst ingesting 6 UHS-II cards at once! I can achieve in around 7.35 minutes what used to take me around 90 minutes using my Macbook Pro 2014 model with it's solo card reader and 90MB/s Sandisk UHS-I SD Cards.
I can highly recommend this great product and the Prograde UHS-II v90 SD Cards!
I made this short real world video highlighting the simultaneous ingest process:
It was very hard here in Australia to find any products like these fast card readers and fast SDCards which is why I purchased direct from Prograde's website. Delivery was very fast via DHL with full shipment tracking available and I received the products in 4-5 days which was really great.
Well done Prograde Digital. Great products and very speedy delivery!
