Review on Efficiently Pack Bearings with GEARWRENCH Hand Bearing Packer - 2775D by Jun Merritt

Some muscle is required to use this bearing roller, but it is necessary. After all, the lubricant we use is non-liquid and useless. It takes effort, but the result is worth it. Batteries are not required; no need for an outlet. Just old-fashioned muscle power, so this tool can go anywhere; under every shady tree. Get this packer. It's made of very thick plastic and will last for hundreds of uses unless you use a hammer or some other stupid method to make it "work". When using this tool for the first time, you will need to "unclip" the butt piece from the bottom of the cup where it is at the end of the build. It's probably stuck because the material is "exhaling," but don't worry; Once it "peels off" for the first time, it's no longer sticky. This is a great, simple and productive tool that all auto repair shops will need and use often.
