Product presentation template

Presenting a product can be daunting, but having a PowerPoint mockup slide can make it easier! It's important to have a visual representation of the product to help the audience understand it better. I once saw a presentation where the mockup slide was the highlight of the show - it was so well designed that it made the product look even more attractive. What have been your experiences with PowerPoint mockup slides?- http://pph.me/kaysar
