Query: Noisy Chopper

The Black & Decker 1-1/2 cup electric chopper was purchased to provide a second chopper. The first chopper was purchased several years ago and has been an excellent product. However, this chopper is a different story. It is a very noisy chopper. It sounds as though the gears have no lubrication and will soon be ground to dust. Also, the plastic lid was extremely difficult to rotate to engage the safety switch.Performance was so bad the chopper was returned to Amazon for replacement. Amazon's performance was very good, including free return postage, and the replacement soon arrived. The replacement was also very noisy but the plastic lid operation was better. Except for the noise, operation is satisfactory. I believe this chopper will have a short life. This experience and similar problems with other Black & Decker products, all made in China, have soured my opinion of Black & Decker.I do not recommend this product.
