I haven't had much opportunity to use them, but what little I did they appear to be a precision tool for the purpose. As had been mentioned in a review, the latch at the bottom of the handle is a bit difficult to close and open; find a better way to secure the clippers closed and you have perfect product.
It's a little more hefty than I expected, but it works fine.
They aren't kidding when they say heavy duty. They are a little hard to open, have to squeeze very tight to unhook bottom latch. I have not had them long enough to give them a five.
Excellent product at a very reasonable price.
A really nice sturdy tool for grooming nails.
