I'll start by saying I've tried other cups in the past and I always have the same issue - leakage. Some of this is down to a learning curve - it definitely takes awhile to get used to the cup. It requires a bit of a desire to make it work! Another tricky thing is sizing. I am 41, never had children and have a pretty regular cycle and flow. I opted for the small size even though the advice said because of my age I should go for the larger. After trying the smaller mooncup for two cycles, I am going to try the larger size. The smaller one just won't stay in place low enough and as I wear it, it moves up into my body and I think that might cause the leaks. I believe in the menstrual cup philosophy and I very much appreciate Mooncup's lack of dyes, additives, or anything "extra" in the product. I'll be back on once I try the larger size. All that to say, the cup is relatively easy to use, love the eco friendly packaging and cloth carrying bag. Excellent customer service, free shipping, quick delivery and made in the UK. I want to support the company so will buy the large size from them and try again!
