I got my FlashAir about 1.5 years ago and have since been bought actually many problems. Making the connection takes a long time and always cancels after 30 seconds, regardless of what I set in the configuration tool. I had several times the problem is that the card is not recognized by the camera and just today the FAT32 partition is then broke down. I was afraid that all the photographs have been lost from the last shooting. But luckily I found the free tool PhotoRec to save my data. Otherwise, if it were well become only 1 star.
I hope that this is a production fault with me, because as an unreliable memory card is useful in any case to vacation photos and still less for professional use!
