I had problem with my old MIMI (bubbling silicone) and i wrote JeJoue, they told me it was defective and sent me a replacement, which happened to be a new model MIMI.
New box is much smaller, cuter and nicer i would say, just different design.
Mimi itself looks the same, but logo is upside down and closer to the bottom.
Now, buttons. There are 3 -plus, minus and function in the middle. it is easier to press these new buttons because they are slightly raised.
It also seems that vibrations got stronger.
Now sad part: function button does not work!
I followed the manual,i pressed it all different ways possible - it simply does not work...
So at this point i am little frustrated...
I am going to write them back and see what they say.
