We recommend Ruby Cup Medium for long, busy days and long trips and hikes, since it can hold more menstrual fluid and doesn’t need to be emptied as often as Ruby Cup Small.

    I wanted to write and say that I wish I had known about this cup before now, because I can only imagine how much time I would’ve used doing more interesting things than staying home and moaning over my cramps.

    I started my period at 9 years old, and I’ve had HORRENDOUS cramps all my life. This first period with the Ruby cup was the most cramp-free I’ve ever been. It was amazing. I actually forgot I was having a period a couple of times. I could wear the cup the entire day at work, and not worry about it at all until I got home. Plus, no leaking whatsoever over night.

    How much money would I have saved throughout my teens and 20s? How much time and how much trash would I have saved?

    I have had my Ruby Cup for almost a year now, and can’t ever imagine going back to using anything else. Why did I only found out about menstrual cups a year ago! They make everything at that time of the month easier. Not only is it convenient and easy, but you don’t worry about leaks or showing or getting caught out, or having to worry about sleeping in the right position.

    I particularly love the Ruby Cup over other menstrual cups (I’ve tried one other). I’ve never had a problem with it, although I prefer the smaller size as the medium is a little bit too big for me, and the smaller is much more comfortable. As some others have mentioned, if you don’t like the idea of some slight staining, get a coloured one.

    Any ladies out there thinking about trying it out, I say go for it! I’ve only had good, positive experiences, and there is not a bad thing I can say about them.

    I’ve had my Ruby Cup for about 4 months now and I feel like it’s already paid for itself. The cost of disposable products is really outrageous. I am SO glad I’m not producing all that waste too. The cup is so comfortable I can’t feel it. I work out with it and go hiking with zero problems. I have worn the cup for a little more than 12 hours without leaks. This is a great product and I would buy more! I also love that a girl in Kenya is helped every time one of these cups is purchased. Genius idea!
