These are our favorite nipple suckers. The E-stim is an added bonus. They are well constructed, and most importantly they work well. They easily get a very nice suction. To the point that they can possibly maintain suction longer than the part being sucked should be sucked. Which is great. Just don't overdo it.

They are not small, at 4" long they are fairly sizable and heavy- when dangling off a nipple. Body hair will interfere with suction. Adding a dab of spit or lube to the base ring really allows these to get some traction. Our favorite aspect of these suckers is how versatile they are! They have been able to get good suction all over my partner's body- nipples, clit, labia, and even ass hole. This is so awesome!

The E-stim verdict: These babies have some power. Proceed with caution, and start on low settings. They can deliver some very good shocks.

Overall, a fantastic toy. If these ever break we definitely will buy another set.
