This toy is very easy to use. I find it best to start with lubrication, as they can be a bit difficult to insert. The first time I used them, I had a bit of a difficulty inserting them and insertion was a little painful. Lubrication definitely helped with that. Once inside, I found they were very comfortable and there was no discomfort at all. You can feel the movement of the balls, but not necessarily the balls themselves. These balls are larger than I expected them to be. I will note however, due to the larger size of the balls, it may cause discomfort for some with smaller vaginas. They should be fine for everyone else. These balls can be worn all day. I insert them in the morning, and take them out in the evening or for sexual activity. I have noticed that I have become "tighter" and that sex is more pleasurable. I personally would not wear these while having sex, but they are fine to wear while stimulating the clitoris. The instruction manual may be hard to read because it is in many different languages. It may take some time to find the information you need. This product is great for beginners.

The material is firm and smooth. There is really no smell to this product at all. There are slits with small protrusions. I believe these are for visual pleasure, as they add no difference to the feeling of the toy inside you.

The design of these balls is very pretty. It comes in many colors, so you can choose what you prefer. The size is a tad on the large side, so it may be uncomfortable for some, but it should be fine for the average user. The size is very good for me and good for beginners.

The best thing about this toy is once inserted, you can't really feel the toy, but you can feel the vibrations. The vibrations feel good, but aren't so much that you can't be in public with them. The only issue I have with this product is it may be slightly difficult and painful to insert.

This toy is very easy to clean. You just wash it with warm water and a mild soap. I use anti-bacterial hand soap. It isn't a bad idea to use a disinfectant toy cleaner. You can submerge this toy in water. It is VERY important that this toy is washed before and after each use.

The packaging is very nice. It doesn't scream sex toy and is informative. There is an instruction manual, but due to the many languages in it, it may be hard to find what you are looking for. It also comes with a free sample of lubrication.
