What I had initially overlooked when ordering it here to a mini vibrator is (13cm), but that was my mistake, the product can not for. The vibration modes are quite nice. Processing acts very clean, but I doubt very much that the vibrator would survive a trip to the shower. Even with the silicone everything seems to be good. Otherwise the product makes a good one, but no durable impression. I'm actually pretty sure that will be broken in the vibrator nem 'half year ... The cleaning is something toilsome and burdensome (for the studs). On the whole, the vibrator is quite nice, but nothing that will knock you off your feet ...
