Overall I am satisfied with the quality of this product. It works as intended.; However, the quality of the supplied fasteners, particularly the cavity wall anchors (see first photo), was disappointing. Two of them twisted and pushed through the wall during the installation of screws. Save time if you must use wall anchors and buy better ones at the hardware store (see second photo which shows an example of one type of screw) and discard the ones that come with them. Also, one of the screws had metal shavings in the drive. a pocket (see third photo) that prevents it from being driven in with a screwdriver. Luckily the chip could be picked out with a toothpick. Didn't bother with glue. I would prefer they didn't include glue and used higher quality fasteners. After the fixing situation was clarified, the installation was easy.
