I was worried 22 cm would be too much, but the flexibility of the CyberSkin makes the length way more manageable than I expected. The suction cup base is seriously strong too, it stayed put on the tile without me having to hold it.

The CyberSkin feels genuinely soft rather than that rubbery stiffness you get with cheaper ones, and the flex makes it way more comfortable at this length. The suction base held firm on the shower wall without slipping once.

The CyberSkin feels surprisingly close to the real thing, and the suction cup held firm on the shower tiles without slipping. Only downside is cleanup takes a bit longer with this material, but the 4.5 cm diameter is just right for me.
