Very happy with the performance, a bit vocal but OK. This is a replacement for one I bought for my son. He didn't read the "after use" instruction and promptly put all soiled parts into a Dish Washer. The result of washing oxidised the metal parts so bad that the result is having to buy a new one. This is why only 3 stars are awarded. Really one would expect to be able to use a Dish Washer after one uses an an item such as this.
