The problem with claims about any herpes remedy is that everyone's system is different and nothing works consistently for everyone. I don't think I have heard anyone directly say they've tried those products or what their results were, but some things do work for some people some of the time.
I'd be careful about assuming that you'll never get an OB, even if that seems to be the case for a while. Your pattern of OBs can change as your body and life circumstances change over time. And even if you're not getting OBs, it doesn't necessarily mean the virus won't still become active and cause asymptomatic viral shedding (making a partner vulnerable to getting it from you).
But hey, just about anything is probably worth a try. If you can afford to spend the money, even if it turns out not to work for you, you might want to give them a try.

If you decide to try any of these, let us know how you make out with them.
