I backed the Dash microSD and SD Card Reader on Kickstarter on 16th November 2015. The project was funded on 1st December 2015 after raising a total of US$11,492 out of their initial goal of US$10,000 from 717 backers.
I chose the US$22 reward level and shipping to Singapore cost another US$3 (despite it stating US$2). So in total, I paid US$25 (S$36).
Strontium recently launched their new range of MicroSDHC cards called Nitro Plus. The Nitro Plus MicroSDHC card is classified under the Ultra High Speed Class 3 specification UHS-1 (U3) for 4K Ultra HD high resolution standard (3840×2160) and hence it has a write speed of at least 30MB/s and read speed of at least 80MB/s.
