With its bulbous, angled head, the Mona is focused on one thing and one thing only: finding your gspot, and giving it great pleasure. I'm happy to report that it's quite successful in its goal.
In many ways, the Mona is a lot like an earlier offering from Lelo, the Gigi (also known as one of my favorite vibes): both target the gspot, both have an array of vibration patterns, both have wonderful iPodesque controls that allow you to control the speed separately from the pulse patterns. They're also both rechargeable and made of sterilizable silicone.
So what's the difference? Well, friends, it's all the in the details (or, in this case, the shape). While the Gigi has a small, focused nub for direct pressure, the Mona's flatter, angled head allows you to, ahem, get up in there and caress your gspot lovingly with the length of the shaft. Also? The Mona is a bit bigger (take note, size queens).
As for me, well—I don't have to choose. And I'm happily keeping both these babies...to alternate depending on my mood.
