Especially if you have had persistent and often drug-resistant period pain like I have. I find that my Livia tends to take care of mild cramps no problem, and for really bad spells, an ibuprofen in combination with the Livia does the trick in reducing my pain to manageable levels.
It's pretty comfortable to wear and they're really discreet, easily hidden under a t-shirt (or not hidden if you don't want to, they have cute case options!) so you can go about your normal day.
It's been a significant improvement to my previous (but restrictive) method of curling up in a bath so hot it is borderline scalding and crying for like 4 hours, so I'd definitely recommend trying it out if you think it might work for you!
I think my only complaint is that it's sometimes tricky when putting it on to find the sweet spot, but that might also just be my own incompetence.
Length of Use: 6–12 months
Bottom Line: Yes, I would recommend this to a friend
