I just bought one and am wondering for anyone that has one how do you like it. A couple of things I have noticed. It will not give me a preview on my Samsung S2 phone but it does connect and I can control camera. My Gopro white will connect with preview. My Samsung tablet will connect with both with preview. I just grabbed a card...not sure of its speed. It recorded fine up to 1080 but at 1440, I only got the sound track. Would that be the card or my 3 year old HP laptop? Yesterday while pushing the wifi button on camera, nothing would happen. I ended up turning camera on and then back off and it has been responding since. Any comments, tips, or anything else I should know about this cube? So far I have only viewed the video on my laptop. Not sure how good the video would be on a larger screen. .
