Having bought the whole boat and baby bath support. I expected to find the same quality in the drain pipe. Alas !! With the water pressure in the pipe and the suction cup comes off successfully keep its dry bath is a miracle. A system of screw would have been ideal. We must therefore hold the attachment plug in the tub during draining which is not very practical nor very friendly for lumbar poor. Setting apart this little quack Babymoov remains a good brand :)
