is that they spoil you.
You don't want to go anywhere that doesn't have one.
Because once you get used to everything being clean all the time, you don't want to go back to the other way any more than you would want to get back in diapers. Because gross.
I've already bought two more of these. One each for my husband and me in each of our two vehicles. They work. You put water in them. You squeeze water out of them. Stuff gets clean.
For me, they're only four stars, though, because of two fairly serious (to me) issues: (1) you cannot pre-fill them - which means you have to fill them in a strange bathroom from a faucet that could well be filthy, and (2) they don't have much pressure.
I'm going to keep looking for a better alternative, but these are much better than doing nothing. MUCH better.
The OA100 (450ml) is the perfect solution for when you're on the go and you want to take the benefits of a bidet with you. No batteries are required! Simply fill the reservoir with water, point, and spray. The nozzle extends and locks for spraying and retracts back into the water reservoir for easy storage. The OA100 is small enough to store in purses, backpacks, and luggage. Recent improvements include additional holes in the nozzle for increased spray volume as well as additional reservoir capacity of up to 450ml.
