Anyone have any feedback on these??? Seems to be a simple, compact, cheap DI system that I may pick up. Plan on using it in the winter only so I can skip the drying part of my cold weather washes. Usually use thick rubber gloves to rinsless wash and dry just like in warmer weather. With this I would use a wash brush with rinseless wash or some kind of regular car soap and just use the DI to rinse and walk away. Probably not faster but definitely will have warmer hands when Im done. Same price as costco but from what amazon reviews say you get an extra filter when buying through costco. These systems always seem cost prohibitive to me, this seems like a cheap alternative.
