I'm using my new Lunette today, but I'll probably switch to my Mooncup UK (B) this evening as it'll be the start of the last 36 hours of my period and the Lunette will be overkill (and I still want to use my Mooncup because I *do* love it) so hopefully I'll get used to it stemless!
I'm getting on well with my Lunette. It arrived yesterday lunchtime when I'd been on for 24 hours. I was worried by the seemingly-vast size (I got the bigger cup for the capacity) when I saw it, but I just put it out of my mind, boiled it and tried... it worked first time (7 fold) without much discomfort going in. I found it slightly harder to fold than my Mooncup, but the firmness meant that it popped open a bit quicker - more of a forceful pop than the Mooncup but not uncomfortable. I got a seal first time. It's very comfortable and I like the flat stem as it's not jabbing me at all I think it's a better design for comfort and ease of cleaning.
I kept it in 8 hours before my first emptying which is getting on for twice as long as with my Mooncup during the second day - I only emptied it because it had started to leak (just a drop but I felt it and went to empty). When I looked I saw that it was only just past the first measuring line so I don't think it would've leaked except the position I was in (slouched on the sofa with my laptop on my tummy and my legs up on the back of the sofa) caused it to lose its seal somehow and I noticed when I stood up. The same thing happens sometimes with the Mooncup.
I emptied it again just before bed (2am) to be sure, and then this morning I hadn't had any leaks at all. I was up to just past the first line again. After I had emptied and washed my cup I got my Mooncup out of the cabinet and filled my Lunette with water to the point it was at and emptied it into the Mooncup - it came up to the holes!
Breaking the seal has been much harder than the Mooncup because it's longer, less squishy, and takes up more room; so it's more difficult to reach to hook a finger or thumb over the rim, but I've not had any pain on removal as I've used folded it to remove it like with the Mooncup.
The very smooth inside of the cup is nice from a hygiene point of view, BUT I've found a couple of times that the angle I'm holding the cup at causes the water to bounce straight out like a fountain (luckily not going all over me or the floor!) without filling it up! So I'm going to have to be careful of the angle.
I'm now really really really REALLY excited about Shark Week coming around again so I can work out exactly how often I need to empty on each day - I'm hoping I might be able to empty just 4 times on the first day which will be a huge improvement from every 2 hours with my Mooncup! I might even take a pencil and paper into the bathroom and make a chart for future reference!
