I really like some of the scents available in this range, and they are really handy to chuck in your bag for a quick freshen-up during the day, plus they're really inexpensive and easy to find at the supermarket.
However, I find that these have extremely poor lasting power; I don't even get a couple of hours out of these. I also think that some of the scents are a bit cheap/deodorant-y smelling (although bear in mind that might just be a personal preference :)), and to be honest I'd rather just wear a better quality perfume that I don't have to reapply so often.
Overall: these can be handy, and some of the scents are pretty awesome, but I think that overall you get what you pay for.
I always brought these during school as they were cheap and had a large range of scents but i seem to find they dont last and the scent is gone in no time and you will find yourself continuously applying. Often gives a rash if on sensitive skin also, not very good. More suited for younger generation
