tl;dr: Worth it, but only from Best Buy. First thing: I don't use this with the intended View-Master software, but rather as a Google Cardboard VR device. And as a Cardboard device, it works exactly like it's supposed to. Split the screen into two parts, one for each eye, get the intended 3D effect. Plus the button on the top right that causes a tap on the middle of the screen where you can't see for various different things, like video re-centering. There are a couple of issues that likely aren't dealbreakers, but they should be noted. First, there's no access to your phone for things like charging or cooling (i.e. ice pack to the back of the phone). Depending on your phone's thermal output or battery use, this could be a very bad thing. Second, there's no way to strap it to your head; you have to hold it at all times. Usually, there's no problem here. But if you want to use this and a Bluetooth game controller, then you've got a problem. All in all, it's worth it at the $20 price point that Best Buy sells it for. Don't get it elsewhere; it's more expensive, and at those prices you'll be better off getting a different Google Cardboard viewer, with charging access and a head strap.

This is not the view master from your childhood. Instead you slide in your cell phone and are fully immersed in 360 degree video. The tech is amazing and really makes it seem like you are in the video as the video moves when you turn your head. What takes this tech down a notch is the amount of good, quality content. You can use any of the Google cardboard apps or YouTube. The vr apps are mostly videos and not that interactive. There's some good content on YouTube, but if you have an iPhone, the YouTube app does not have Google cardboard view on ios. Construction is solid and the phone fits snugly into the unit. Everyone was amazed at some of the demos. Just wish there was more content.

Overall, a fun experience for the kids. Not big enough for an adult who wears glasses, but fine for a child with glasses. The software is OK, but you're also open to any of the google vr compatible apps as well. For some of the VR experiences, you need a lot of room to walk around. On the goggles, it would be nice if there was a head strap to hold them up.

My son enjoyed watching this but he also wished that it is like the oculus or other VR tools that will have a strap that he could put around his head and be handsfee. Otherwise, it was good for its price and our son appreciated it. We like the samples it came with especially the one pertaining to space. Our young son found it cool.

I had been interested in trying a Google Cardboard viewer, but was hesitant due to most products being made of actual cardboard. I appreciate the sturdy feel of this plastic design. I have no complaints about the clarity of the display, but for anyone wondering, the focus is not adjustable on this model. I spent very little time with the included demo "reel," but I've been able to open any app designed for Google Cardboard. As a fun bonus, the design is a throwback to the Viewmaster slideshow toy I had growing up. Bottom line, if you're intrigued by the VR phenomenon, this is a great way to try it without making a major investment.
