Review on SUPLIK IPad 2/3/4(9 Tablet Accessories for Bags, Cases & Sleeves by Joe Merculief

The design of this item works in every way except one: when standing alone on its two black back supports it is at a 90 degree angle to a table or desk ( e.g. looking straight ahead). It should be closer to 70 degrees (i.e. tilted back slightly). Most eyes are over a countertop or table (except for small children who are seated in adult chairs) and therefore need to look down to see the screen easily. An adult would have to rest their head on the table to look directly at the screen. I need to find a way to cut off part of the two black supports so they lean back 70 degrees. Anyone have a saw?
