Unfortunately, I realized that when you have multiple tablets or smartphones, you can not really control where something has arrives. And the images send again via WLAN? NO CHANCE! Once sent, is sent, is sent. So in my case I had a tablet, a phone and a laptop ... on the laptop and the phone never arrived and what I needed forever to notice the (partially!) Have landed on the tablet the images.
I can transfer the data via WLAN again not even on the computer. Totally useless.
As cheap "add-on" for a cheap camera for people use only a smart phone, the thing may be really great. Means for example works great! Therefore, 2 stars.
Who really wants to retrofit a camera with Wi-Fi, reaches for the less mature, but functioning Transcend card or directly to the Eye-Fi Pro ... which I now really have to think about it again.
