    “The 12 modes make a bigger difference than I expected.”

    I like being able to switch between different modes depending on how I feel that day. The controls are simple, and it only took a short time to get used to. It feels much more versatile than I expected from such a compact device.

    “It feels discreet from ordering to everyday use.”

    Privacy was important to me, so I appreciated the discreet packaging. The device itself is compact enough to store without drawing attention, and having 12 modes gives me plenty of choice without making it difficult to use.
