This toy needed a lot of lube, but once inside, it stayed inside. I wore it first while taking a shower and then under my clothes to do things around my house. I would probably not recommend it for anal use since the tail attached to the last ball feels a little flimsy, and I was slightly worried I would rip it off. Personally, I did not find the vibration to be particularly powerful, so if you need a lot of stimulation, I would not recommend it. I used it for Kegels, and would definitely recommend it for that.

The material is a very smooth silicone. Smooth enough that I did not need any lube to insert it. It is very firm, almost a little too firm, especially with both balls inside, but it really does make you feel full. There was a little discomfort sitting down, but lying down or standing, it felt just fine. I didn't have to clench too tightly to keep it inside me even though I wore it while exercising. If you have experience with kegel balls, these are a good size, if you're new to kegel balls, they may be a little on the large side.

I purchased it for kegel exercises since I was curious whether vibrating balls vs the regular ben wa balls would be more interesting. It is very pretty, from the color to the silver accents on it. The balls are about the size of kumquats, and they feel very smooth going inside and out. If you are a beginning user, I would recommend using only one ball at a time since both balls stretched me fairly well. Overall, it doesn't really look like a sex toy, but if TSA sees it in your carry-on, they may be suspicious about its shape!

I was hoping the vibration would be stronger. Even on the highest continuous setting. I wouldn't use it as a sex toy since I didn't feel much stimulation, but for the purpose of kegel exercises, while walking around or exercising, it performed very well. Far more interesting sensation than the regular ben wa balls, but not enough stimulation for me to feel any level of arousal. It is pretty quiet once inside you, though.

I have purchased two EdenFantasys products (the ones that seem to come from EdensFantasys rather than a third party), and they sent a cute little black bag with the toy. It also came in a very pretty, discreet black box that I repurposed and am using to store one of my longer dildos. It's held up well with soap and warm water, but getting in between the balls can be a little tricky because of the angles.

I loved the packaging, honestly. The order this came in, I bought the Oula, the quivering spheres, and two thrusters. The two thrusters came in a rather obvious packaging without a storage option. Both the Oula and the quivering spheres, once out of their external packaging, were both in discreet boxes and came with little bags. I repurposed the box for one of the thrusters that DIDN'T come with packaging. It came with instructions, but honestly, it's pretty easy to figure out.
