Foot File "Laser Foot" 2-sided, 04-036 Zauber

I had a similar grater from another manufacturer and it served me well for many years. When I was looking for a replacement, I found out that it was difficult to find a similar product (in fact, Zauber is the only option I found). There are no complaints about its performance, the grater works well. However, I also came across a poorly glued one and one side came off after the second week of use. Attempts to reattach it to the sticky side were in vain, as it keeps coming off again and again after use. So, it seems that with this product, it's a matter of luck with the batch. It's a pity that there is no quality alternative available yet.
