In the past, I used a type of monitor with balls, and gradually the ball became elliptical, and in the end it was. Next time I bought this item to make it feather type so that it will not fail. Suddenly broken from the root suddenly at the 4th month and the cooling water blew out like a fountain from the water chiller, it became a serious thing. If noticed late it was where the welding machine broke. I think that the product is poor, especially because it is not doing impossible arrangement by bending the hose. I think that it would be nice if you could describe what is immediately possible to describe the item.
