I am accustomed to the heavy duty kitchen strainers or yesteryear so when I ordered these I was expecting something similar. Unfortunately, these are very thin and feel cheap and the largest one isn't as big as the old school strainers (which is what I wanted). They work ok, but I feel like I am going to dent them, so I am very careful with them. And I don't like how the holes feel, they don't feel smooth. They do drain decently and I use them once in a while.
I said I wouldn't recommend them, but for the price of $15, they are ok if you need a strainer set that you use occasionally. However, I would definitely NOT pay $30.
