Product review (5 stars): Wonder no More
For delicates, this item provides an incredible alternative to the normal machine options.  With warm water and detergent, the washer creates an vacuum that extracts dirt to what must be close to 100%.  A couple rinse cycles removes the excess detergent and dirt. leaving the clean items ready for drying.  When used for stockings and other delicates, this washer avoids the damage that might occur with conventional washers.

Anyone can assemble the item with minimal difficulty.  One can also attach and detach the drain pipe with minimal difficulty.  I suggest locating the washer in a bathtub where it can be easily filled and drained.
