Review: They work great - I always bought the cheap nail clippers at the drug store. What a difference! These cut with a clean edge and catch the clippings. No more nail pieces flying all over. I like that I don’t need a nail file to smooth out the jagged edges that cheap clippers leave. If you need clippers, get these!
Review: Affordable security - Works well with all of my important apps without issue. The only gripe from these old crippled hands is some fidgeting to swing it open. Other than that the fingerprint works like a charm, as do the rest of the features.
