Without a focus ring or any ability to focus, apps and images are blurry when using the Sharper Image VR viewer (Model no. 1003469).
I purchased this particular viewer on sale for $20 (suggested retail $50). So at this price point a lower quality product is expected. Lower cost in this case means the product is made of plastic materials and the product is made in China. This VR viewer features a cushion around lenses and fits all sizes and model of smartphones whether you have an Android or iOS phone. The biggest trouble is the lack of a focus ring. Without the ability to focus images, this product in my view, is virtually useless.
For this product I give it 1 STAR (out of 5)
