Still working excellently
Color: Black
I have had it a few months now and i am happy i have not had any problems. It is still working well. It still is easy to use. Its still has a sharp blade. It still has a nice grip. The fact that its compact and quaint is the reason i bought it not to mention the price. I definietely give it 5 stars.

Works but moves easily skids
Color: Black
Works well but Base has no anti skid grip. It slips on the counter easily. What kitchen counter top gadget has no anti slip base?? This is proof Amazon Essentials are essentially low grade products.
