The ribbing on the upper shaft stimulates the inner anal muscle band, and when combined with the sensation of the knot, creates an amazing experience.

Would be better if smaller.

Would have preferred this exact thing shrunken down! Really like the ribbing, but the ball is way too large for me! Please make a smaller version! Shorter too!


This toy is absolutely incredible. I have a few tantus toys, ( their quality is unmatched) the oooo's givin from inserting the last ball is unexplainable. Took a couple of tries to get it all in, but oh man i have never came so hard in my life.

For me, frustrating

It’s a beautiful toy, like all tantus products. So I had to give it five stars, but this did not work for me. To reach the ball I experiencing too much discomfort and was wishing the toy was shorter before the ball.
I have been able to insert the general,both firm and normal, so it’s just a disappointing personal quirk.

Takes a bit to get past the knot

A word of caution for any potential purchasers - the average rectum is around the same length as the top shaft and a quarter of the knot. In other words, you stand a decent chance of hitting a wall, or more accurately a bend, before you can take the knot all the way in. But, after owning this toy for around a year, I finally took that knot, and it was a great feeling. The key is gentle but steady pressure, and maybe a warmup with a longer, thinner, more flexible toy beforehand.

Love it!

Just arrived today and warmed up a little with my Tantus Echo. After switching to the Fido, I had taken the knot and had it fully inserted to the base in only a few minutes. No issues with the base size for me. Nice fit!
