I'll step in here: I sell them.
I have had very few service calls on this product: all were related to the power cords, and only one was warranty. The others were from gardeners cutting or chopping the cord, hardly the tub makers fault. BTW - the cord is easy to replace...
But they do seem to satisfy the folks who have bought them from me, and they are the hands-down favorite of my delivery team!!
If there was a weakness, I would say its the small filter. You will want to ask for an extra one to be included, or simply purchase a spare so you can swap it in. This is not a big deal since it's a small tub.
