How is this better than a ceramic or bamboo soap dish?

Metal will not split or shatter the way bamboo and ceramic can, and the angled shape lets water run off instead of pooling under the bar. The coating also resists mold.

Does it fit large soap bars?

The dish is made to hold both large and small bars, and the brand says it works with most bar brands, not just its own.

Can I put it in the dishwasher?

No. The brand says to rinse it under running water and warns against dishwashing with harsh chemical detergents.

Will it stick to the shower wall?

No. It is a freestanding dish with no suction or adhesive mount, so it rests on a shelf, ledge or tub edge.

Is it good for travel?

The stainless steel build holds up to a suitcase being knocked around. The brand notes that rubber bands can substitute for a stand at the destination if you want to pack lighter.
