I LOVE Doc Johnson products, especially dildos. Lately, though, my favorite dildos are usually made of a dual-density silicone (eg Vixskin). These have a soft feel, but a firm inner core--kind of like Cyberskin or UR3, but non-porous and easy to care for.
Does Doc Johnson have any plans to create their own dual-density silicone? Simply recasting some of your most popular toys in a dual-density material should generate LOTS of sales and new customers, too!
