I picked some of these up in Thailand, not knowing what they actually did since all the writing was in Thai!
We used one just the other day, and I can't say it was that great. Firstly, it was bright pink, which might do it for some, but just made me laugh!
Secondly, my man came quite a bit before me, which was probably due to the fact that they are thinner (so I suppose these would be good from a man's perspective).
I can't say I noticed a reduced latex scent as advertised.
As a last point, it was actually really really small (maybe because it came from the East to be stereotypical, as this description says easy fit?) and left a huge ridge where it had cut into my boyfriends penis! Not good.
I suppose it does the job, but I would prefer something a bit more exciting.
