Review (4/5): Noisy but works
When using this in my ears there's a lot of squeaking and clicking and scraping sounds so if that's the sort of thing that bothers you just stick with battery operated trimmers.
I wanted this because I was tired of battery operated trimmers breaking down and having to buy a new one all the time especially in this day and age of shortages and not being able to buy replacements so I'm glad I have this but I am going to buy an electronic 1 because I just don't like that clicking scraping screeching noises in my ear.
