Does what it's supposed to... but nothing is perfect.
First of all, I received a Norelco shaver with a cleaning unit and a bottle of this solution, so I was not afflicted, but yes, this is a useless product if you don't own the unit, unless you feel like dipping your shaver in the fluid and turning it on repeatedly (if it even is made fro that).<br /><br />Though this product does clean and lubricate the blades, it's best to manually clean the separate heads and blades by taking the shaver apart once in a while, as the solution can not break down or remove every bit of "gunk" in the head, which is common sense.<br /><br />Oh, and the price on Amazon is cheap too.
