Not so great, better off with hotel shampoo
These little tabs seemed like a great idea to wash clothes in the sink while traveling, but they don't work so well.. They're not very strong. It takes 2 tabs just to get a single pair of underwear clean. Another problem is that even a few drops of water, the the slightest wet fingers, will cause tabs to dissolve in the dispenser and stick together. You're better off using a little hotel soap to wash your clothes or bringing a single larger, dry detergent sheet and breaking it into smaller pieces.
