Bests & Worsts Reviews from Amazon

First of all, I think this product is definitely worth five stars. At first I was worried that this would be a poor quality product in the term of price but it made me very happy when I got it. The suction of its suction cup is very strong and stick to flat surface very firmly. I will give you some advice when you use it. You can add some liquid so that it will suck better. I use a disinfectant spray to do this. Good results! You can also use it in a vertical position if you have good skills. It has 3 sharpening stations, which are completely incomparable to other similar products. It has a groove of tungsten carbide. Tungsten carbide is a very hard metal that can grind off excess metal on your knife. If your knife is very blunt you can use it. But this product also has a ceramic groove. The texture of the ceramic is very delicate. You can use the ceramic slot to grind your precious knife, it won't hurt your knife. I personally like the function of its sharpening scissors. I have several sharpeners but none of them have the function of this grinding scissors. I often need to use scissors in the kitchen so my scissors become very blunt. But now it has become as sharp as ever.
