Ex Input:
Very shallow. Advertises other things can be cleaned with it but reality is it's way too shallow to fit anything in except phone. Had to take phone out of case. Disappointing. Wouldn't waste your money on it. Would have been nice if glasses fit in it.

Ex Output:
1

Ex Input:
Exactly what I expected from a knock off Google cardboard product which costs 1/4 the cost of the original. Works great for what it is. It was a great introduction to VR and convinced me I needed to invest in VR as this was enjoyable to view videos and games through. I have since purchased a much more expensive model with built in headphones and adjustable focus/pupil settings.

Ex Output:
5

Ex Input:
Very hard to use because it's too wide for your braces to really move around. Gonna use mine since I bought them and suffer the uncomfortableness. But won't purchase again. Great "idea" though.
