These are fairly big (1 1/2 inches in diameter and almost 4 1/2 long) and firm. I found them a little painful to insert and remove because of that. They are steel balls with rattles inside of them coated by only about a 1/8 inch of silicone coating, not as comfortable as solid silicone of the same diameter. For women that can take more, this might be fine, especially those who have had children delivered naturally.

As a solo sex toy I liked them, because I felt full when I used these with my clit vibrator, with out the distraction of managing a dildo. When I wore them at work they definitely added a little spring in my step & not because of any orgasmic feelings, but it was fun to see how I could make them move and the resulting sensations. They are good for mild stimulation that results in a low level of arousal. If I hadn’t left them in too long and gotten rather sore, I would have been in the mood for more rousing play with my husband afterward.

I suggested using them with my husband, but that idea didn’t appeal to him.

As an exerciser, I noticed some strengthening of the PC muscles, and I suspect with regular and frequent use these would really help. Because they are connected, they cant rotate around each other or bang into each other like with more traditional, loose Ben Wa balls.

These are best used for exercise or mild stimulation while walking & sitting doesn’t do much. Be careful when first using these; I couldn’t take more than about four hours at first. I found trying to use the restroom while these were in uncomfortable, so I definitely wouldn’t leave them in all day.

The string makes for handy removal; I couldn’t have gotten them out without it. The silicone connection between the balls might not be up to a lot of wear and tear & I haven’t used mine much in three weeks and there are some marks on the connection where it might be coming apart so be gentle with them. I also found that after I left them in for long periods of time they developed a mild bend that makes them a little difficult to get situated comfortably now. Leaving it in warm water might straighten it out.

I’m not just jumping for joy over these Royal Balls, but they are a good beginners Ben Wa ball type exerciser.
