Review on 🔧 ARES 70004 Precision Oiler Pen: Accurate Lubrication in Tight Spots with CLP, Ballistol, and More by Dan Quiceno

Looks well built and works great. When I received mine, it had a small burr on the threads for the needle tip cap that would have caused small cuts on the o-ring, leading to premature wear. Remove the burr with a small file. Filled with WD-40 and pressed the top button. Releases a tiny drop of oil, just right for a sealed bearing/sleeve or a dirty potentiometer. Edit: less than an hour after pouring when flow started around the button. It's a shame it can be a fantastic tool but if it needs to be drained to avoid spilling the oil everywhere between uses it won't be of much use.
