Wasn't sure about the 15ml bottle at first, but a little goes a long way and the water-based formula doesn't get sticky. The warmth kicks in within a couple minutes and builds nicely instead of hitting all at once.

The 15-minute window is actually accurate, which surprised me since most products overpromise. A little goes a long way with the water-based gel, and it absorbs clean without any sticky residue afterward.

Wasn't sure about a liquid formula at first, but this one is water-based so it wipes off easily and doesn't get sticky. The clitoral stimulation kicks in within a minute or two and stays warm for a good while.
