I bought this as a Christmas present for my 4 year old, luckily it arrived in time for me to take a look before my daughter opened it.
The mat was not a bad size for one child but probably not great for two. There are 2 games, I am not sure what each game was supposed to be as the instructions that came with the toy were very bad. The music is likely to drive you mad within 5 minutes and the only other sounds I could find were by stepping on the kittys, each would produce a one note sound - drum clash, cymbol sound etc. The rest of the mat is just that - a mat.
There are ports to connect the mat to an MP3 player or HiFi, I am not sure what added value this would give as no cables are included.
The fun factor would be limited to about 2 minutes. I thought this was the kind of mat that would light up so the child could step on the lights to dance.
For the money this product is very poor value.
