DARK KNIGHT Electric Intelligent Automatic Telescopic Cup

Get plenty of lube for this bad boy or you might burn your wee wee from the spinning, twisting suction motion. If you're girthy you may need to work on the lower settings to get the fit adjusted. If you are long the just know it won't all fit inside but it works just fine on the head and little past that. It can be a little loud but it will get the job done right. Perfect for those nights when plans get canceled.

So first off, yes this product is legitimate. Secondly, it works extremely well. While in use on the full power setting the battery fully charged lasted me about 1.5-2 hours before dying. Very smart and clever design idea.
