I love the (very mild) scent of these and they absolutely do what they are supposed to. The only downside is the packaging: I dropped one and the glass shattered on the tiles, leaving shards anywhere. On reflection, this is not great for a product designed for the bathroom, particularly if you have kids around.
I have sensitive skin and easily get a rash and itchiness with most deodorants (roll on or spray), after using them for several days. With this Nivea sensitive and able to use it everyday without ever developing said itching. Smell is very mild, mainly acting as an anti-perspirant rather than having an active scent.
If you don't want to be smelly then use something like this. It does hide the smell so it does work. The only down side I can see is that because it's glass if you drop it it will break so don't drop it since when you're likely to be using it you're likely to be in bare feet on a surface where it will break easily so don't do that.
