I bought this grip to play The Binding of Isaac in handheld mode and it's doing the job very nicely. The overall feel of the switch without the grip is a little thin and your hands get tired quickly (or mine do, I have short fingers so need to roll my palm when I'm doing very fast inputs!), so when I picked up this case those issues were instantly erased thanks to the more bulky, gamepad feel. It's not perfect, such as having to wiggle my headphones into the socket as the case doesn't quite line up, the material isn't of the highest quality for comfort but then it does say on the box it's designed for protection so fair enough, and putting it on and taking it off again could have been made... safer. It all feels a little dangerous really, where no danger is actually present but still, had the grip come in two halves which clicked together round the back of the console, I would be giving this 5 stars. As it is, it's a really decent case for when you're out and about or even when you don't want to stare at the television anymore and want something smaller, less in your face.
Here's hoping Orzly sort out the design so it slips on and off much, much smoother (again, two seperate pieces has my vote!), because this company retail some of the best Nintendo accessories!
