Review (5/5): Durable and does exactly what it claims.
This works great. It'll never give you an amazing haircut, but it can give you an even buzz. I got this to get me through the pandemic thinking if I used it twice it would pay for itself. A half dozen haircuts in it still works great.
There is a limit to how good of a haircut you can give to yourself, but this does as good a job as I think is probably possible.
