The 12 cm size is perfect for someone like me who's still getting comfortable with this kind of thing — the tapered shape made insertion way easier than I expected. Small enough to not feel intimidating but still does the job.

The tapered shape made insertion way easier than I expected, and the suction base actually grips the tile so it stays put. For something this compact it doesn't feel flimsy at all.

The size is just right for starting out, and the tapered shape made it way easier than I expected. The suction base actually holds firm on a flat surface, which I didn't think would matter until I tried it.
