A very useful product. Very happy to have bought it. It did leak once but I realised that i did not understnd the diaper mechanism. But as i discovered how to make the baby wear it, I found the product amazing. Baby sleeps peacefully and is comfortable wearing it. Sleeps in it, as good as he used to sleep in disposable diaper. Lasted more than 5 hours. And i need not worry about rashes or other skin problems for baby.
