Review: Excellent - Very sharp and a great price. Lasts for a long time
Review: These Actually Work - I bought a different brand last time. Half of them didn't work. But the ones that did work are handy as heck. I tried this 30m pack from DIYSELF, the first 15 anyway, and they all worked flawlessly. I assumed that all of these different brands were made in the same Chinese factory. But these seem to be better quality. Now I just need to be better at not misplacing them.
