I've had a small Yuuki cup for a couple years and I'm very happy with it, but I read recently that Yuuki changed their cup design a while back to make them stiffer, and that now they are offering both the older softer model and the newer stiffer model. Well, I would like to know how to figure out which style Yuuki I have, in case I ever need to replace it. I've never touched any other menstrual cup other than my Yuuki, so I don't know how to tell if mine is stiffer or softer. Considering this, are there any other markings that can be used to identify the different models? Also, my cup came with the stem completely trimmed off, so I can't use stem style as an identifier. And does anyone know when exactly the Yuuki became stiffer? I bought mine used in February 2011, and it was less than six months old, so it was most likely purchased sometime in late 2010, probably between August 2010 to December 2010.

Also, I noticed they now have something called an Infuser Box you can use in the microwave to sterilize your cup. Has anyone used it/is it worth the money? I often skip sterilizing my cup because I feel really awkward sterilizing it on the stove, since it looks kind of odd and I feel bad putting my cup into a communal cooking pot. This would be a good alternative to that, but I'm wondering if it's worth the money (it'd be about nine dollars to the US including shipping).

This video shows the difference between the "old" soft and the new "firm" (although, *now* they are available both ways, too--confusing, I know!):


Maybe you can discern which is yours by the "squeeze" test utilized in the video, or perhaps by the "opaqueness" she describes in the video.

As far as microwaving, I don't *typically* sterilize by boiling. However, when I have to (to sell or in case of infection), I use a coffee mug. Either pouring boiled water (from a teakettle) or microwaving in the mug for a few minutes (2-4 minutes, YMMV--your microwave may vary, ha!) works, too.

No need to purchase a specific item for this, IMO. Also, a quick rub with rubbing alcohol after the process gives me an extra satisfaction of "super squeaky clean" sanitizing.
