The most recent toy I tested is the LELO Mia 3. Let me tell you who it's really for.
I read a lot of reviews from bloggers that said Mia 3 is powerful and rumbly. Even on its sales page, it says "8 powerful pleasure settings." Well, it is not.
It is as powerful as Mia 2, and its max power is about the same as Tango X middle speed, but more on the surface.
That being said, I think Mia 3 is a big upgrade from Mia 2 because of the silicone cover.
What I mean is that Mia 2 was a good vibrator for the more sensitive users who need a very low starting power, but that hard plastic shell made it more intrusive and numbing, kinda paradoxical.
Mia 3 fixes that problem. Now you have a bullet that has a gentle vibration, and the silicone muffles it and feels much better as a sensation.
Other than that, it is light, beautiful, and discreet, and it makes almost 0 noise, so it is a great travel companion.
TL;DR: Mia 3 is a good bullet that fixes the design problem of Mia 2, but I recommend it only to those who are in the very sensitive to sensitive range and prefer pinpoint surface vibration.
Here is my full Mia 3 review with more photos and details on how it feels.
