I just wanted to post our story with working with Je Joue on a defective MiMi. We've had our MiMi since last December and it started not vibrating nearly as well even when fully charged. We contacted Je Joue via email and provided them with our proof of purchase and they promptly sent us out a new MiMi, and the newest generation at that. And it only took about 4 days for us to get our replacement. I have to say, that it's one of the best customer service experiences I have had and just wanted to let you know that it was super easy smooth and if any of you have any problems with your Je Joue products, let them know. Super awesome and easy to work with.
