I bought this to trim my child's hair, but it didn't suit us, so I only used it briefly once and then put it away. There are some areas on the main body that have yellowed slightly. I have confirmed that it works, and I will ship it with the batteries removed (requires 2 AA batteries). I will clean it to remove any remaining hair before listing it, but please refrain from purchasing if you are concerned, as this is a manual cleaning.
