I bought these for my wife some time ago as a "cute" thing to play. We then forgot to use them until this past weekend. We were playing a board game that required me to blindfold her and then tease her in a way that I had not ever done before. I noticed these in the toy box, and voila. These small silicone stimulators did the trick very nicely.

While she was blindfolded and lying on her back, I turned each of these on (she said hearing the sound but not knowing what it was before I placed them was fun) and placed them on each of her nipples. Her immediate comment was, "Oh my." I then proceeded to tease her nether areas with a separate toy. She immediately cried out and came. She told me afterward that the combination of these two vibrators buzzing on her nipples sent a very noticeable buzz straight to her clit. When I then applied the other toy to her clit, that was all she wrote, instant orgasm.

After we played with them, they were easily cleaned off with warm soap and water, then put back away.
One thing I should mention: these things are not easy to see how to turn them off and on. There is a small switch that goes from the outside of the toy to the inside of the toy that you push in toward the nipple when you want to turn it on, and then do the opposite to turn it off. However, the switch is very small, is the same color as the toy itself, and is right in the middle of the vibrating section so it is hard to see and feel. We both had a good laugh about two grown people having trouble figuring out how to turn them off!

One final note on the negative side: these have what are obviously tiny batteries and there is no way to replace them. You should therefore consider these as "disposable" toys.

We did note that these do not stay on well, as there is nothing really to make them do so other than the material's natural stickiness to the skin. If you are using any lube, however, this will make them fall off. We suggest that you use them as we did, as a teasing toy while the person lies on their back so that they do not fall off.

Also, due to the small battery power, they are not overwhelming like a real clitoral or g-spot vibrator, but are rather little buzzy friends.

Well, the batteries still haven't gone dead, and we have used these little toys a couple of times. In our opinion, they are worth the buy as a toy that you know will only last a couple of months.
