Very happy with it especially at this price point. I work in HVAC and needed something small for hard to reach places to remove/install schrader cores on air conditioners. A big plus is that they have integrated multiple cores into the product itself, which is pretty cool. They're definitely easy to lose when you're out working in the elements. The packaging is great too, I'll update my review if necessary, but for now I'd definitely recommend it if you're in a hurry!
