Product review (2 stars): Not intended for heavily soiled items.
I am a welder, and work in a fabrication shop. I use the Wonder Wash, but not as intended. I have to use it basically as a hand washing tub, as there is no agitator to remove dirt from soiled items, so I fill the tub, let them soak for a half hour, then just use my hand to agitate the clothes for two, or three minutes, drain, repeat for a second cycle, drain, and then refill to rinse the remaining soap, and drain again. It will fit one pair of jeans, a long sleeve shirt, socks, and underwear. Don't try to put more clothes in, as even hand washing in the tub will not get them clean if you do.
I might rate it higher, if I were to wash gym clothes in it(smelly, but not soiled), and could use it as intended, but the way I use it, you could just use a large bucket instead and save the extra money.
I paid $20 for this, and would not spend more than $25 on it, even if I was to use it as intended.
I have owned this for nearly two years, and it has certainly paid for itself. The build quality seem fine. I heard a crack on the plastic base months ago, but to it's credit, it is still holding up to daily use from me, although I don't use the lid, nor do I rotate the tub other than to drain it from the top.
It dosen't totally suck, but it does get tiresome at times washing clothes manually, and daily.
