Don't know what you need, until you see it. When I saw it I knew it was going to be a hit. So true! My mom is just in love with this shop. Now her tablet is in front of her where she can see it better, she doesn't have to hold it or put it down, it no longer falls off her knees to the floor, kids can't grab it and run away with it, and most importantly, it doesn't sit around on your knees and slowly send microwaves into your body! It's really cool, really useful and makes a great gift. We didn't even know we needed one until we tried it for the first time and fell in love with it. It's worth it, so cheap! UPDATE: It lasted about 4 months and then broke in half. Just say!
