Is it urgent? No. I just like to boost for good products and warn against poor ones.
Is that geeky? Likely, but life's too short to want to be like other people, to live others' lives in replacement of one's own. And life's too short to be embarrassed—for very long—about flying one's freak flag.
I'm sure I've used other, generic glue sticks before, and if I were very diligent I would run out and pick some up. I know Office Depot has a house brand, and Target probably carries alternate brands. I'm only reviewing what I happen to have on hand.
