PromptBox

Check pricing and availability: B&H

It's light, it's portable, it's robust, it's inexpensive -- and it's one of my favorite tools when I'm working with non-professional on-screen talent (like a local business person trying to reach his or her target audience). PromptBox punches WAY above its weight class and is untouchable at the price, perfectly sized to work with my Apple iPad Mini 3. Highly recommended.
