The first thing I want to say about these is DO NOT use them anally. While it says on the product page that they can be used anally because they are made of Elastomed, it is most certainly not recommended. These are strictly for vaginal use because they are weighted and pose a huge risk of becoming lost in the rectum if inserted. If you're looking for a toy that can be used both vaginally and anally, look elsewhere. No one wants to end a night of fun with a trip to the E.R. and a feeling of horrible embarrassment.

With that said, there are many different uses for Smart balls, both for vaginal muscle strengthening and stimulation. They can be used very discreetly for strengthening the vaginal muscles- put em in and go grocery shopping! Just remember you might get a huge twinge of pleasure here and there, so be prepared!

Whether you're using them for exercise or stimulation, an ample amount of lube is required upon insertion, as it can be a bit difficult until you get the hang out of it. But no matter how much experience you have with your Smart Balls, you'll still need the lube, simply because they aren't shaped like much of anything your vajayjay is used to.

Personally I found they were great to use during anal sex (of course when inserted vaginally.) They provide an extremely tight feeling and a light "vibrating" sensation which makes anal that much better. Another way my man and I were able to use them was during oral sex, which I must say felt amazing. I was going to put them in to run some errands, and my boyfriend said "Let me put them in," then did that and then some! Needless to say, the combination of tongue on the clit and weighted balls inside the vagina is amazing.

Smart Balls are made of Elastomed, which is odorless, non-porous and phthalate-free. The balls are smooth, firm and sturdy, and the piece holding them together, which is also made of Elastomed is flexible since it does not encase anything. There are four grooves on each ball that provide additional sensations. These are extremely sturdy, and I think they will outlast most of my current sex toys because they are so well made.

The design of the Smart Balls is what roped me in. They come in a variety of awesome colors, but I picked the very feminine magenta and pearly rose. The majority of my Smart Balls are pearly rose, and they are accented with the magenta on the four grooves on each ball. They are comprised of two weighted balls, measuring in at 1 3/4" long each- a total of 4 1/2"- with a circumference of 4 1/2" for each ball. They weigh approximately .3 lbs, so don't worry about going on the scale with these puppies in! A string, also made of Elastomed, is attached to one end for retrieval purposes. The retrieval string is attached very well and certainly serves it purpose, however ugly it may be. I'll save that for the next section, though. They feel very similar to Chinese stress balls when moved around- the weighted balls move freely inside their encasement, providing the light vibrating sensation.

Personally, I felt they were a perfect size for me. However, based on other reviews I've read, they may be too long and therefore uncomfortable for smaller women.

The one complaint I have about the Smart Balls is the retrieval string. I find it to be just plain ugly, and it detracts from the colorful, fun design of them. It somewhat resembles a tampon string to be honest, which makes them slightly less sexy when used for partner play. My boyfriend actually made a comment regarding the string, saying it almost confused him for a bit until he realized I was wearing my Smart Balls... so make sure your partner knows you have your Balls in before approaching them for some sexy time, or they might be a bit concerned about your string.

Insertion can be a bit difficult, so like I said earlier- USE LUBE! I absolutely love how comfortable they are once they've been inserted. I actually forgot I was wearing them for a while, but that quickly changed once I moved! Going up and down stairs is certainly an interesting sensation, and I'm actually very curious to try them on an elliptical or treadmill. Why not work out a few extra muscles while you're at it?

As far as strengthening your pelvic muscles go, you can certainly feel them working if you are in motion. However, they require somewhat extensive use in order for you, or your partner to be able to feel a big difference. All the more reason to slip in your balls, ladies!

Removal is somewhat uncomfortable for beginners as well and you want to do it slowly and gently. Then you'll definitely want to immediately clean them, as you'll find they have a tendency to collect, er... love juices.

Smart balls are very easy to clean. I rinse mine with warm water, and then follow with an antibacterial toy cleaner. Dry them off and place them somewhere safe. You don't want them floating around in your panty drawer, so if you have a sachet you can use to keep them in, or even the box they come in is perfect for storage. One of the best parts is that Elastomed is compatible with both silicone and water based lubes, so you get to pick your poison!
