The menstrual cup thing wasn't my 'thing' until I won one - another brand. I loved the concept, and my body and me hate tampons and the like, so this seemed like a great alternative. After failing with the one I won - I did my research to find one that had fabulous reviews to give it one last go before giving it a miss, and I'm so glad I did. I found MoonCup, it works and I haven't looked back.
I purchased the MoonCup and it arrived in a box, with great instructions and a cute pouch for storing the cup when not in use. Using any cup is a bit of a 'fiddle' at first, and it absolutely takes time to work it out - but I highly recommend reading the instructions that come with the moon cup because they're awesome. If all else fails there's loads of tips and tricks on the internet for getting a menstrual cup to work for you.
This cup is super comfortable once in (I can only compare to one other brand), It's firm to insert, and what makes it really fantastic is that its silicon is really firm, so sits tight once inserted so I know there's little risk of leaking as long as I've inserted it correctly (it takes practice and understanding the direction all the body parts point, to point the cup in the right direction as well). The important thing with inserting the cup is to relax - it's something I have to consciously tell myself sometimes.
I have a very crazy heavy cycle and can honestly say the MoonCup made coping with that so much easier and less stressful. I'm no longer in tears as I deal with the heavy period. I couldn't and wouldn't go back to icky tampons and pads. I feel better for the change, and feel better the planet is better for my change.
