Product review (2 stars): the mesh bags twist up terribly, with the clothes balled up on opposite ends ...
Based on reviews here, I put all clothes into mesh laundry bags to prevent twisting/knotting.  Even when clothes are in mesh bags, the mesh bags twist up terribly, with the clothes balled up on opposite ends like some kind of figure 8.  Sometimes the edges of the mesh bags catch under the agitator.  Powerful agitator, by the way.  Like others have written, there do not appear to be any fill line markings on the device. You'll learn from experience what the max level is, because it comes out the end of the drain pipe (even when in the upright position).  Also, quite unfortunately for me, the counter space next to my sink is tiny. This machine, which is not huge, does not fit on my counter. So, I have to pull out my work table, put it in my cramped kitchen (to be near both water & electric source) and keep a 5 gal bucket nearby for drainage.  It does work, but not as expected and doesn't seem suited to my needs.
