Saves on battery costs but RRP is $9.99

This is a great idea but I would not buy from Amazon - at 11.99 they are charging $2.00 more than the recommended retail price from Vtech

Should be standard with game itself

Silly that it is not included with original toy. The batteries don't last long so this is a must!

Piece of Junk.

I have purchased 2 adapters and both of them quit working after just a few weeks. The toy runs well off batteries, and they actually last a while. I would invest your money in batteries instead of this adapter.
