We have a lumilove, bought for ds2 as a birthday present by the gps. When we opened it on the day we discovered it was broken (the led and switch had come away from the animal and was rattling around inside). A quick call to the site we'd bought it from and they said that there were a whole batch exactly the same. We got a replacement which works fine but because of the problems with the original one we I am reluctant to let ds2 carry it around. It is nice though and ds2 likes to watch it change colour, but I think there may be better products out there that do similar things.
