Using Smartballs is an enjoyable way to exercise your pelvic floor muscles. I bought my Smartballs shortly after reading that strengthening your pelvic muscles can lead to more enjoyable sex. In addition to working out your vaginal muscles, the inner set of balls provide a mild vibration that is just enough to remind you that they're there. You can slip the Smartballs in during the day as your own little secret, or you can put them in before a hot date to be sure that you'll be aroused all night long.

I loved the way the Smartballs feel so smooth that they're almost soft. They're made out of silicone with small ridges around both balls. The material is very firm, and the Smartballs are only flexible at the middle connector, allowing the Smartballs to be inserted at a slight curve.

My Smartballs have never smelled, but I'm always very quick to clean them after use so I can put them away. The material isn't porous and is very solid, so I don't imagine that they would end up smelling.

I love the design of the Smartballs! In fact, I think their cute design is what led me to choose them over any other Kegel ball set on the market. The balls are a little large, so I typically need to get myself warmed up before I insert them, but once they're in, I feel as though they're just right. The shape is also a perfect shape; I like that the balls are not perfect spheres and are instead more of an egg shape (just barely). I think this is an easier shape to get in and out than a perfect sphere would be because it's more gradual.

I consider this toy to be a discreet one, but I'm mostly basing that off the fact that it isn't phallic as all my other toys are. I don't think I would be embarrassed if anyone came across them, but I also don't keep them out. Their small size and discreetness make these toys suitable for travel.

I personally love the inner set of balls in my Smartballs. I often find myself dancing around with them in just so I can enjoy the vibration. One thing that I do have a hard time with is getting the Smartballs out, though. The string at the end is used to pull the balls out, but you also have to make sure you're relaxed when doing it. I seem to have an impossible time doing this and end up working really hard to get the balls out.

Because the Smartballs are made out of silicone, they're incredibly easy to wash. After use I always just end up wiping them down with a toy wipe or washing them at my sink. The original box the Smartballs come in includes a little clear plastic mold for them to sit in. Rather than throwing this little case away, I kept it and store my Smartballs in that before I put them away in a drawer.

Of course, because the Smartballs are made out of silicone, be sure you don't use a silicone-based lube when using them to prevent breaking down the material.

I've found that Fun Factory always has the cutest packaging to go with their cute products. The box had easy-to-understand instructions and, like I already mentioned, included the little plastic "case." The case isn't anything extremely fancy. The plastic is more like the plastic used in Barbie packaging, but it works great for simple storage. I wouldn't recommend using the package as a gift unless you were giving someone the set of Smartballs, in which case I think slapping a bow on the box would be a perfect addition to the sleek packaging design.
