Ansolut recommended and its predecessors far superior. Device on iOS Ruck Zuck and without fumbling, the transmission speed is top. Had the old EyeFi and Transcend. Also encouraging is the noticeably better workmanship compared to the old EyeFi cards. Full-HD video goes, but this card is (as I know no WiFi SD card) suitable to the fast modern DSLRs auszureizen. At the 7Dmk2 as you then already noted at 10fps that these cards are not racing machines. But they are not intended.
