noisy,
battery doesn't last as long as other b/p's (battery is smaller)
the pump involuntary kicks in now and again, annoying, and eats the battery juice.
water goes quick.
but, it is sturdy and well made, and if only using for awkward jobs, rather than
all day, like me, then go for it.
i'm still mostly using wcw b/p, but i don't think they sell them no more. .j.
