The product is generally friendly, the only problem being that the vertical arm (the one on which the tray is set) is not properly secured in place, the problem from the design. Indeed, pat on the arm in question, we can change the horizontality of the tray, which of course is not desirable. Apart from that, he has the mouth and is easy to mount. I would, however, appreciated the opportunity on the wall bracket to set the horizontality using slightly larger hole ... but I quibble ... I am generally satisfied with the product considering the price
