This device is designed for easy use. Just use warm shower water. Hold a flashlight towards your ear and the bug will crawl towards the light. Just like you went swimming underwater and added some circulation. It's gentle and very refreshing.
Obstructions block sound.
By allowing more sound to enter your ear canal by removing the blockage of dirt, dust, and earwax, it becomes less obstructed. They are lubricated with silicone lubricant. Both are very efficient. The small one is compact and fills quicker, while the large one irrigates longer. 8 year olds can use it.
