We loved the concept and the product and purchased one of each Telugu and Hindu for our 3yr old and a few more as gifts. We take learning mother tongue very seriously and are very glad to come across this product.
A few thoughts since we started using the product. We are happy to elaborate if you need clarification. We have already been promoting this product through word of mouth.
1. We liked the light weighted nature of the pad. Easy for kids.
2. The buttons sometimes can be hard for the younger ones to press correctly.
3. I can understand that this would add to the weight and cost of the product but give it a thought to add backlight feature so that it can be used during travelling in the night.
Our daughter has been screen free and she is 37 months old. It is getting harder to keep her occupied this winter as the nights are looooong in Vermont. We like to not introduce her to the pads with screens (like the ones from Leapfrog) as they are not too different from a smartphone or a tablet.
Please keep up the good work. We will keep doing our part to promote this important product.
