This device is anything but an accurate tool for pedicure. The sharp tips of the tongs carry a high risk of injury. Moreover, it takes an excessive amount of force to abzuknipsen nails.
The clamp is not very well made, that is, the cutting surface is not particularly well-honed and the spring mechanism for self-opening the pliers after tweaking does not work properly, which greatly complicates the use.
I'm going to re-buy a clipper and dispose of this product.
