Product review (3 stars): A Bit Pricey but Works Well
This is a pretty good way to wash some clothes but got some issues.

The handle is too slender.  I got arthritis coming and it smarts!  Rubber palmed gloves help but be even better if handle were 3/4 or even 1 inch.  Foam around the handle would be most excellent!

Handle comes loosens partly from the plunger after only a few strokes!

Plunger only has two holes, maybe 1/8 inch.  Seems to me it would be much better with, maybe 4 more larger holes.

Aside from all that, cleans well and excellent workout!
