There are a lot of things I hate in toners: a floral smell, an overly-thin formula, and feeling like I'm doing nothing more than splashing water on my face, which makes this toner perfect for me.
The scent is not floral in the slightest, and has a pleasant scent I can only really describe as "venom". It's somewhat chemically (in a positive way) and somewhat citrusy. Not a hint of rose whatsoever.
The formula itself isn't thin like water, but it isn't thick like cream either. It's thin enough to drip if you hold your hand at an angle, but won't go splattering around if you whipped around suddenly.
It also has a very subtle tingling sensation after I use it. It isn't the kind of tight burning you get from stronger foundations, but something pleasantly light and enjoyable.
Lastly, you get an incredible amount for the price of one bottle! The bottle contains a full 150mls of the toner, and it will last for months and months. I would definitely recommend it.
