Query: Would never switch back to tampons

The Diva Cup is awesome. It no longer is a burden to have my monthly period. I hardly notice to even have the Diva Cup in, and it is superior for so many reasons. It is much more comfortable since you can't feel it, and is less drying than tampons are. It is less messy, more environmentally friendly, you can go pee while you have it in, they contain no bleaching chemicals, it is more cost-effective, it is more comfortable for working out, and it is easier for travel. I don't have to worry about carrying tampons, and I don't have a white stringhanging out when I change in the locker room. I no longer have to carry tampons around in my purse, and I don't even have to buy tampons at the store. I have only tried the Diva Cup, so I don't have a comparison for other brands. After having a menstrual cup, I have no reason to ever go back to using tampons. It took a few months to perfect the technique, but no difficulties beyond that.
