What to know before buying

Listing details to confirm

The listing gives the size as both 89.0 millilitre and 3 Fluid Ounces, which are presented differently. It also gives dimensions and weight in two conflicting formats: 46 x 46 x 93 millimetres and 0.25 Pounds versus 4.57 x 4.57 x 9.27 cm and 113.4 g. Confirm the selected pack details if exact measurements matter. Customer feedback is divided on fragrance, greasiness, ease of use and value, so those preferences may affect suitability.

The overall rating distribution leans positive, but it does not establish why individual customers rated it as they did.
