Great hunt @alikoc07!
This would be a hit for pregnant mothers. This helps the baby in the womb have interaction and perhaps have a healthy development and additionally, this adds joy to both the parents especially when the baby kicks or perhaps a mark of a foot appears on the stomach of the mother. Definitely, the price is so right and on top of that it works for both iOS and Android devices. Kudos to the designers of this bellybuds.
