The suction cup on this actually holds firm on my tile wall, which I didn't expect for something this size. The 18 cm length with the two testicles at the base gives it a really natural feel in hand, and the detailing on the head is well done.
The suction cup is way stronger than I expected, sticks solid to the shower tile without slipping. The vein detail on the shaft really does feel realistic, and the 18 cm length is honestly perfect for me.
