Review (4/5): A tool I never knew I needed!
I tend to have a built up of callus on my feet and have always used a manual grinder to thin down the callus and smooth it out. When I found out this product existed, I was very intrigued.
Not only does this product help me reduce my callus, it also includes different tips with a wide variety of different functions such as nail filing and nail polishing. It is pretty small and portable, and the use of a USB connection makes it more versatile. Also something to note if you are interested is the fact that this grinder does not make too much noise.
Now to talk a little about what the product could improve on, the inclusion of a wall plug would have been nice. I imagine most people have some sort of access to a USB plug but if you do not, you are going to need to buy one. One other issue to point out is that the length of the cord could ideally be a little longer. You can use an extension to mitigate this problem or just sit near a USB connection.
Overall this product does what it advertises. If you are trying to look for something that will help you save time this will help you do that. I cannot speak about the long term durability of this product, but what I can say is that I have been using it for a couple of weeks and have not ran into any issues. Overall I give this product a 4 out of 5 stars. It is a great product to consider and if some of the flaws I pointed out were not present, I would give it 5 out of 5 stars.
