## Customer Reviews

### ⭐⭐⭐⭐⭐ Washer and it works
*by S***Y on May 23, 2025*

Work great for me

### ⭐⭐⭐⭐⭐ about 80% stainless steel, not 100% 304
*by R***. on April 27, 2025*

Confirmed. They are stainless steel. Magnet barely sticks at all. Though, they would be better if they were 100% stainless steel instead of like 80-980%

### ⭐⭐⭐⭐⭐ Quality
*by R***Z on May 3, 2025*

Very good quality, thicker than the other brands.
