I have been using this nasal aspirator since my child was a baby, and now he is 5 years old, and still using it without any problems. It is easy to use and cleaning the nasal aspirator , just insert the batteries, and the silicone nozzle will not hurt your child. I always take this outside on family days. It is okay to use this in public when my child has a runny nose. It is cleaner than using a towel to clean my child's runny nose. Definitely recommended to everyone ❤️👍🙏🏻 thank you so much
