My brother-in-law sent me one as a gift, years ago, and I regarded it as sort of "meh", because I didn't even have any RFID cards at that point, and that's not really part of my threat model, I guess. However, the banks subsequently foisted "tap to pay" cards on me across the board, and I also have a US Passport, and I recently aquired an NFC Yubikey, so now I may have more concern. The slipcovers are nice, but I really fell in love when I found out there are Faraday Bags available from a few vendors of "tactical gear". The Faraday Bag comes in several sizes; most are large enough to hold at least a smartphone, if not a laptop. So you can really envelop a serious device or collection of devices in those babies. I have placed it on my wish list.
