I got this vibe a while ago (a month? Two? I have no concept of time so I really don't know, lol)
I played with it once, let it sit for a few days or a week, then tried to play again and the battery was dead so had to charge it. This happened maybe 5 times. (Already enough to annoy me. All my other rechargeables keep their charge between uses!)
Anyway, I think the toy is completely dead now. I've been trying to charge it for the last few days, and it won't turn on at all. Just makes a sickly sounding squeaky noise. At first I thought it was that the charger was getting bumped loose but now I'm pretty sure it's just not charging at all.
Good to see you have had success with with getting a replacement. I'm going to email them an see if I can get one too!
