This is the most cheapest VR set by Google. The product is made by the simple quality cardboard so it is not reliable for long time it can easily bend by any pressure or load. This product is not comfortable for long time use just like if you are watching the movie on it the cardboard is makes the scratches around the eyes there is no arrangement of any soft rubber on the side wall of the cardboard. And lens is used is not fixed properly it moves in the cardboard gaps so sometimes the angel of picture is disturb. The design of product should have be more comfortable. But at the value of money the product is OK.
