Product renders are a great way to show your product off without having to hire a photographer. It gives you the flexibility to literally do whatever you want with your product. Below are examples from various clients I've worked with over the last few years.
I find the creation of product renders to be quite therapeutic. It reminds me of painting, how you have to really look at the thing and how the texture is and how reflective it should be, how the colors blend, and so on.
