I found that leaving this toy entirely in, while I went about daily activities to be perfectly comfortable, albeit a bit distracting (in a good way). I've used it most frequently while laying in bed, with one end of it inside of me, and the other outside, tugging lightly on the loop periodically. It left me feeling like I had gotten a work out, and was a bit of fun foreplay, before I amped things up.

This toy has no give at all when you clamp your muscles down on it, which I didn't find problematic, but might be worth noting. Since I'm a person who doesn't typically have problems being self lubricated, the slightly matte surface of the toy didn't give me any problems, though some users might need to apply a bit of lube before inserting it, for comfort. The toy had no noticeable scent or taste at all, either.

The piece connecting the two balls of this toy (writing that made me giggle), is flexible, but considering how short the length is, it only allows the toy to curve ever so slightly, because one ball will bump into the other. As far as length of the toy goes, some people might not find it comfortable while sitting down, because the inflexibility of it may cause it to bump into parts of your anatomy in an unpleasant way. I've only had very minor issues with this so far. Because it's so small, and so easily cleaned I would rate this as travel friendly also. Quite discrete

As mentioned in other sections of this review, I found it pleasant for exercising both while walking around the house with it in, as well as while laying on my bed. I also have enjoyed having the toy in while using a vibrator, because it gave my body something to flex against, and the free moving parts inside of the ball provided pleasant sensations, and it also gave a slight feeling of fullness, which I enjoyed. The overall performance of this toy is precisely what I expected, and how it's described.

I keep this toy in a drawer on top of a folded hand towel, with some bottles of lube and condoms. It's recommended you clean it with soap and warm water, and the only lube I've used with it so far is a water based. It's ok to use a silicone lube as well. I've noticed that if you use the item for any particular length of time, I get quite ah, juicy. So when removing it I tend to have a small towel on hand, because bodily fluids gather around the piece that holds the balls together.

The packaging was perfectly clear, showing what the toy was, how to use it, and what not. I chose not to use the box it came in, because I sometimes spontaneously decide to use items in the middle of playing, and didn't want to have to fiddle around with a box.
