I've got one, and have used it. It's okay, but bulky and single purpose. A 5 gallon bucket with a washing plunger (can't recall the name, but I've got one of those, too) is better in my opinion (the bucket has many uses).The WonderWash is another alternative. I haven't used one personally but have talked with people who have and they seemed to be pleased with it.
Sounds like you've built yourself a churn. :wings:I use a 5 gallon bucket with a gamma lid. if traveling just add clothes, soap(very little), and water. the motion of travel especially off road does the trick. if I am at base camp I have a gamma lid with hole in the center and a toilet plunger.
