The same type goggles as you linked to in Best Buy can be gotten from eBay directly from Hong Kong or China for $5 bucks, they are not that great, I've used them with Litchi and my Inspire, it's very tough to get good optics and adjustments enough to fit everyone's needs. The Zeiss goggles that are advertised on Best Buy have gotten great reviews and are about $40 at BB but you can also get them new and used on eBay fur good amount less. I find goggles to be very difficult, specially VR goggles that use your phone. I opted to go the HDMI route and purposely purchased a pre owned Nvidia Shield with an HDMI port and Yuneec Skyview goggles they have a great clear screen (single screen) which works so well it allows you to see focus very well.and they are found from various sources now for about $50, I think Yuneec has phased them out. I thought I was getting a great deal when I got them and actually paid like $75 if I remember correctly. But out of the phone based ones I would think the Zeiss will have better optics as they manufacture photographic lenses for the top camera manufacturers, All that said, keep in mid flying with goggles is illegal unless you have a spotter you cannot fly alone.
