I used this once when the one I wanted was sold out. The Nivea one was the next best thing because I wanted a stain free deodorant. It was close to the price of the other one I wanted, so it was still affordable. It had a light, pleasant scent and wasn't overpowering. It was also easy to carry around in the bag.
I sprayed it on after I had a shower, focusing on my underarms. It was gentle on the skin, but it left white marks on my clothes, which was annoying. It also didn't keep me from sweating for long periods of time. I was pretty disappointed with this spray, I felt like I wasted my money on it.
I will never use this again. It doesn't really do what it says.
I used the full bottle of this more out of laziness to go to the supermarket to get another one. I found it didn’t combat the b/o smell very well. It smelt great after first applying but after any physical activity it wears off quickly. Even without physical activity it only lasted me a few hours. No white marks however so it does do as it says, perhaps it just wasn’t suited to me.
