BAD construction in my opinion. It was used 3 times. It also started to make grinding sound. This product can not risk any form of bending to it which at times can happen when you attached to a wall to use it and if the angle titl too far off, the slim mechanical bar arm inside it that is the link to the top vibrator at the head link to the bottom portion of another vibrator will snap. And the one I got snap. And since it is almost totally sealed, you can not know what happen to it snapping nor can you fix it without cutting the penis portion OPEN. So there is no way to repair this pricey product. TOTALLY NOW WORTH IT 3 use spread over about one month. Each time not more then an hour. Not going to trust this kind of stuff anymore. i read many complaints of such devices but different brands. Think I paid $90 for it? Sub=standard. How to repair? For sure no warranty or anything.
