This feels like a farce. Jon gave it no chance and didn't even show how it worked. In what case is holding the cover and dangling your tablet important? When he stood it up in stand mode he did it completely wrong. He just pulled the cover off rather than flip it around to the back like every other cover works, which works really well even though there is no side attachment. You're doing people a disservice with this video.
Here's an alternate perspective. I've had a very different experience with this case. It stays firmly in place unless you purposely push it off, what did you expect? Personally I have not had an issue with that in the two months I've had it. Also it's great when gaming as it substantially reduces the heat your hand has to absorb when attached to the back. It's nice that it holds to the back with magnets, something the iPad cover does not do and because of that that the back flaps around, which I find annoying.
Also of note because it doesn't have a specific side to latch too you can chose either side when using as a stand so you don't have to put the soft side down. This is especially helpful in the kitchen for use with recipes where the counter can be dirty and stain the inside of the cover.
If you like covers and are OK with the price, get it, its worth it. An official cover really makes the complete package with the tablet. Cheap cases off of Amazon don't offer the same experience and end up making it larger, heavier and cheaper looking than the official cover does.
