If you just want to shave completely, it may not be the best product on the market. As well take a razor.
I am looking for in my case to give me a "3-day beard" and the mower with its adjustable shoe allows good. I also shave some parts of the face, and it works very well: Just cut the hair with the mower if is too long, and then pass the razor!
I even used the mower on other parts of the body, and I am satisfied: no risk of failure with or without hoof, as long as you stretch the skin.
In conclusion, this is the trimmer tool + shoe that I like about this product. The razor being effective, but only if the hair is not too long (it may explain some negative comments ...). I recommend!
