Query: UPDATE - broken mop replaced by Bona customer service

Length:: 0:27 MinsThe cleaning solution itself gets five stars, but the mop garners 1 star. This mop snapped at one of the joints on its third use. The mop didn't assemble very well either, come to think of it. Customer service was very responsive, I am happy to report. They have offered a replacement mop. We'll see what happens. I will follow up with an update to this review.July 2011 UPDATE: It took some time, but Bona replaced the broken mop. I have been using the new mop for a couple of months now and it is still going strong.
