SaSi charging experiences?

I just got a SaSi and very excitedly went to charge it. To my frustration the plug does not fit securely and keeps popping out. When I finally got it seated without moving, it doesn't show the red "charging" light. I can get the red light to come on by pressing the plug down hard and squeezing up on the opposite side of the toy to keep the pressure on. But as soon as I let go, the light goes out.

I'd love to hear experiences from anyone else who has a SaSi, before I consider returning it. Is it possible that it is charging successfully even though the light doesn't come on?

Thanks!
