Bottom-mount Label Strip like this often offers the advantage of fitting multiple shelf profiles, saving time, money and the stocking of multiple strips. From that perspective they can be a good choice. But this strip rides above the shelf surface as a menacing “tripwire” to the access of large heavy items like the Laser Printers merchandised here.  You should consider a lower profile. And this particular top-load design lacks the roof-overhang of more sophisticated label strip. Dust, dirt and spills are free to enter the strip. A lesser strip like this might save some minor cost upon purchase, but requires later cleaning and more frequent replacement when torn off the shelf.
