Review (2/5): Don't bother with this one; spend a little extra and get a quality replacement.
While the packaging was impressive in that there was no way this would get damaged in shipment, the product itself leaves much to be desired. I installed this replacement part on my fully charged razor and.... nothing to be impressed over. The new foil/cutter replacement head did not shave nearly as close as you would expect from a new part, and it even pulled a few whiskers. My last replacment head did not do that, ever!
Thinking about sending this one back. Don't be fooled: this part is not at all worth the money you save. Just spend a little bit more and you won't regret it.
