I don't use Facebook so I didn't know it was polycarbonate.

Good Morning,
Hope you all had a nice weekend.
Here is the plan for this week. We are going to share some pictures of the different models throughout the week. By Friday you will have seen all the different models/images and then the following week is when the full specs will be released along with pricing and pre-order on the website.
We will have more information later this week on the exact date and time for pre-order. I know a lot of you want it all now, but hang in there and let's have some fun this week....I know we are enjoying all the comments and the very creative guessing and photoshop editing

(I couldn't resist)
This is the ProVari Radius in Onyx Black. The top, bottom and button plate are Stainless Steel and the body is made of a strong and light weight polycarbonate that won't chip, flake or peel (the color is all the way through). The device is
very comfortable to hold and no taller than a ProVari Mini. You will also notice the large main button, which is easy to find and comfy as well. For those who like buttons that click, we offer the best of both. The large main button is our classic style button and the two smaller buttons are clicky.
More details later in the week.
