I've had a few of these now (wired ones) which always break because the wire is so poor quality. At least the ones I had have had powerful vibrations with a nice solid motor. These have very tiny batteries and you can see the motor head is smaller than in my others, leading to very weak vibrations. They also don't always work - I turned on and several times had to shake them about to get working. I took them apart and passed 3volts into them to see if I could get them to be more powerful but they just aren't up to it. I ended up throwing in the bin.
Not bad :-)
A good basic sex toy at a very competitive price is the phrase that springs to mind. It was fun using these on my partner and watching her squirm with delight. We have an active an adventurous love life but, yes, these added a little spice. So far I've been too chicken to let her try them on me
My good lady wife has always had very sensitive nipples. We decided that this item would make a good addition to our "box of toys", Performance wise its good value for the money. Its certainly not state of art but its added some fun to our sex play and is still working well.
