Review (4/5): 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).
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.
Oh, and the price on Amazon is cheap too.
