Right, well I will have me say on the subject!
The splash on lotion is the cheapest. You are MEANT to use a lot of it for it to last (hence why it's cheap). The aftershave, also a splash on, is much more persistant than the splash on so requires far less applicated. The EDT has a spray and needs only a small amount. All three have great longevity IMHO and smell great.
I recommend those who like Brut should get hold of a can of the Brut anti-perspirant as that will literally last all day once sprayed under the arms. The deo also lasts a good while too. I use these particular Brut offerings for work and they really do the trick.
As for the Brut image... well in the UK I find it has had a jump in popularity, even with the younger people, and women seem to really like it. My girlfriend is 23 (7 years my junior) and when I first wore it she used to love it. She never knew it was Brut but when she eventually found out, she was like "eeeeuuuuwww!!!". It's a sad attitude to have but she is now used to the concept and agrees it's actually a very nice scent.
So I guess the moral is, lads, wear Brut but don't tell the women (or men if that's your thing) what it is you're wearing, and you're onto a winner!
PS. I highly recommend people seek out the other products in the Brut range... particularly Brut Oceans and Brut Musk (deos)... both are actually very good, especially Oceans!!
