My daughter liked how the dog made noises and light up, but the vibrating scared her mainly because I think it tickled her hand and she didn't know what to make of that sensation. My son thought they were just cool!
I tested this out with some of the daycare kids with the same results. Some where a little scared of the vibrating, but they all wanted to get it right and hear the congratulations!
My only issues were that their wasn't an off for the volume or the vibrating. Some of the kids were scared when it vibrated in their hands and I had to hold it for them, so being able to turn the vibrating off would be a good option. Also, sometimes when the babies are sleeping having the toy volume on can be an issue and it would be better to have a mute option where just the eyes light up. Other than that I don't have any complaints! Check it out for yourself and let me know your thoughts!
