Firstly I really like the smell of this product, its fresh without being over powering, it also did not leave super noticeable white marks which is a bonus. I do not think that this product worked any better than other deodorants in the sweat department though. I found that I still sweated in the hot humid Auckland weather, however the sweat did smell pleasant due to the product. My partner found the same with the men's one, it smelt nice but didn't protect against sweat for him.
As for the 48 hour claim. I think the scent of the product did last on my underarm (yes I sniffed my pits throughout the day to check :) from the morning well into the next morning but as for 48 hour protection from sweat I think that is a little bit reaching.
Overall the smell is nice, but I do not think it does all that it claims and that is why I have given this rating. I do not think this product would be the first I would reach for in the isle.
It works very well. It smells so good that you will no longer need to spray any perfume. And it lasts the whole day.
