Silicone is a quality non-porous material which is resistant to bacteria. It is a bit stiffer than an elastomer, and a little less flexible for transmission of vibration. It should only be used with water-based lubricants, as a silicone one can form a build up after multiple uses resulting in layer upon layer of silicone. Silicone items can withstand higher heat, some are made to be dishwasher safe. Most Vibratex items have a battery pack and or motors which cannot be put in the dishwasher.
