Luna beads give very subtle vibrations, more subtle than I was expecting. At first, I wondered if they had been worth the purchase. I immediately jumped up to the two heaviest-weighted balls without any issue. However, I did discover that, when worn for prolonged periods of time, as well as combined with foreplay, these beads do build and sometimes surprise. I don't get anywhere near "O" levels, but they do make everything a bit more exciting beforehand. Of course, the health benefit is that you're also strengthening the pelvic floor with zero concentrated effort. In the end, I'm pleased with my purchase, even if it was far more subtle than I anticipated.

Tips: Use lube to insert, lay down and relax. Put them in well before any anticipated shenanigans, or just for kicks. Then move! Don't just sit there, give the beads reason to vibrate!

The material is smooth for easy insertion. Once inside, it's easy to forget they're there until they rattle around a bit!

I like the design of these ben wa balls. The smoothness of the material makes for easy insertion with lube to help the muscles pull them inside. The harness and pull string make for easy removal, which is a huge plus over most ben wa balls.

The great thing about this toy is how discreet it is. You wear them inside you, so no one knows just how much fun you're having. There are also no batteries to replace. Physics does the work for you! Just insert and go. My only hesitations are the occasional 'knocking' noise might be heard in unusually quiet situations, but it can be shrugged off as something in your purse or pocket. And again, they are extremely subtle, so don't expect a 'big finish' from them by any means. If, however, you want to combine them with some clitoral stimulation or spanking, they may help you get there!

Wash thoroughly with hot water and soap after disassembling the balls from the harness. It comes with a pouch for storage, though I only keep my 'active' beads in there, as it's too small to fit all four and the harness. Feel free to use a toy cleaner as well. I use coconut oil for lube with this one, which works well with both the ball and harness materials.

Lelo packs these perfectly with easy-to-follow instructions inside. The box also makes for excellent storage, or when being presented as a luxury gift. VERY nice.
