I had something in my sink to hold my washcloth but didn't like how it took up sink space. This was the perfect answers and now I can hang my washcloth on this and it hangs just enough over the sink so the drips stay in the sink. Also enough room for my scrub brush and sponge. Very happy with this purchase.
