Review on Portable Urinal 3-Pack for Travel: TravelJohn Disposable Solution for Men, Women & Children by Mike Brumfield

The newest aspect of this product is the powder at the bottom of the bags which thickens and gels when in contact with a liquid such as urine. The major downside of this product is the capacity of only 28 oz. Because I'm on a specific medication, I need to drink about a gallon of water every four hours, so I need to urinate frequently. It wouldn't be difficult to make this product more spacious - all it takes is a bigger pouch and more powder. If you use it in a car, you can't be sure that urine won't fall out of the bag when you put it aside for later disposal. The package cannot be sealed. The only guarantee that urine will not fall out is the gel-forming effect. It is difficult to see the benefit of using this product over urinating into a bottle.
