Invisible companion is best used for couples wanting to add a little more sensation between the sheets. It is nice for the shower too. A great position to enjoy the Invisible is doggie style (shower or bed). I think the toy is more for the female, due to the fact that my husband complained about how uncomfortable it is to wear. Its definately a toy for more advanced users, considering we even had a little difficulty figuring it out!

Invisible has a studded end that should sit on the clitoris for stimulation. The rings are bendable and stretch to fit sizes, but my husband felt it was too tight, tighter than most cock rings. Which made for a complainer during sex. When you get off the material tends to get sticky and very hard to clean. After one use we had a lot of scrubbing to due. We tried soap and water, which didn't work all that well, and then we tried a toy cleaner, which I think combined with the soap and water helped get it all clean.

The design is a bit confusing for a beginner. It takes some time to figure out how to actually make this work where both partners are comfortable. The ring next to the clitoris vibrator is to fit around the penis, and the second ring is to fit around the testicles. The studded end should sit properly on the clitoris, but if using the missionary position it can tend to dig down and hurt. Other than the discomfort of not stretching enough to fit "all sizes" and that it dug into me while in the missionary position, it does work well for doggie style.

There are no different settings for the vibrations, so what you have is what you get. It can be slightly disappointing especially if you want a little more. The vibration is intense enough to stimulate both myself and my husbands testicles, which he did say was enjoyable. Even though it stimulates well, it is quite quiet. Due to the fact that the fit is very snug it can make it difficult to put on and take off.
