Has anyone used GW3Dfeatures Add-In?

I have been looking for a way to get accurate conics in SW and GW3Dfeatures Add-In lists conic sketches and surfaces as available features. Has anyone tried this product? I am tempted to look at the fee trial but I'd like to get a little information first that doesn't come from a re-seller or from the manufacturer.

This is a link to the product if interested:
