Looking somewhat like a torture device, most people either love it or hate it. The vast majority of my clients have loved it, however! It stimulates the nerves in the scalp, causing goose bumps and shivers, which many find pleasurable (that's also what a few won't like about it
). It's easy to clean/disinfect with bleach, and mine collapses to fit in its own little storage bag, which was included with purchase. Mine stores very easily on the side of my doula bag. I bought mine at Bath & Body Works for $6 USD, but it is often priced more expensively, at around $20 USD. I recommend The Tingler Scalp Massager, especially if you catch one on sale!
