Just ordered a pair of these instead. Appear to have better reviews, bigger, and supposedly stick on better.

I hope those worked out well for you.  Do they stay on and have the vibrators continued to work for a few weeks?  Are you happy with the stimulation?

I found that these definitely do stick well on larger breasts.  Both devices can be charged at the same time and the charging ports are easy to find. The soft silicon rotating heads give my nipples a great and very erotic massage.  So far they have been going for more than half an hour. The vibration is not strong, but I use them for erotic nipple stimulation, and that works for me.  They should be considered nipple stimulators and not full breast massagers.
