In the trash after a single use
Size: 11 Holes
For context, I’m a seasoned woodworker and always evaluate tools with the price in mind. This seemed like a good deal and in fact when it arrived, it looked and felt like reasonable quality for the price. Unhappily, the first bookshelf I drilled was off from side to side by almost 3 mm which would make a really wobbly shelf situation. It took a while to figure out what was happening, but I finally realized the metal bushings that guide the drill bit are so soft that they cored out from contact with the bit even though I was cautious to not put the bit in under power but to get it in the bushing and aligned before drilling. Still, the bushings started angling immediately. So when you then use those angled bushings to set the pin for the next series, it’s off by a little bit. Then the next is off by a little more…. By the time I drilled holes up and down a 6’ high shelf, the bushings were out of square, the holes were 3 mm out of alignment, and the shelf sides were firewood. Back to the drawing board and this goes in the trash, I’m afraid.

Love this stuff
Color: Black, Size: 12" x 10'
I use a manual wheelchair and have some hand strength issues. This shelf liner is all over my home not just as lining to protect surfaces but cut in various shapes for everyday use.
The kitchen and bathroom have them for a little more grip to open bottles and containers. In the dining room, to put under plates or bowls, so that don't move around while I eat.
The living room has a small toolbox, which holds a number of different sizes and shapes for the tools and for items like cables, I'm connecting to entertainment devices. For this purpose alone, it's definitely cheaper than the Mercedes version of grip material Dycem, as well as each Disabled Catalog's version of stuff that's just like this shelf liner. It's also a far better quality item than Dollar stores. Additionally it works great as it's described.
SPECIFIC TO NAMED USE:
As shelf liner it does take a little time to flatten out and stay in place in drawers. I use it puffy side up, which creates small indentations from items with any serious weight—stereo equipment comes to mind. A lot of the indentations will hold to the item that created them. To leave the liner where it lays, I always slightly lift each corner/foot of the item on the liner and release the liner, before lifting the whole object up.
Imo the black looks better under devices on glass shelves.
Microfiber dusting cloths are used on the liner and seem to do a pretty good job. That's said, with a weekly normal dusting done — weighted items are dusted where they're reachable, light weight shelved items moved, dusted, and open areas of liner on shelves dusted.
PLUS once a month (1x) all items are moved thoroughly dusted and liners are "shaken out" and wiped down with a DAMP cloth. Shelf liner needs to be 100% dry, before putting it back on your shelves, especially before putting back electronics.
The wet cloths used here, have just enough moisture to remove any remaining dust after a liner shaking but it doesn't feels wet to the touch, after damp wiping.
But to err on the side of caution, the first shelf's liner and contents, are restored after the last shelf is done. Then each shelf subsequently follows.
Personally as someone disabled, I find it to be a great item that does two jobs well.
