Excellent product used them for a long time disappointed you only do the 4 pack ? AND. Their not included in the shave club subscription:  Any reason? 

The easiest shave I’ve ever had 

Have tried many blades, gillette fusion are quality, always get a good clean shave with them, would not try anything else now

I’ve had problems for many years trying to get a good razor that doesn’t cut & nick my sensitive skin but the Pro Fusion 5 is the Best I’ve ever had and will continue to use it! ( I’ve thrown all my old razors out now )

Love these blades always give a good clean smooth shave, Even though I like to shave twice a day the blades keep sharp for a long time. I recommend using very hot water to rinse the blades this gets rid of all hairs in between the blade. Cold water isn’t as effective. 

My first purchase and the goods arrived as promised and in original packaging and what a great product and price Will be using them Again and Again 

Very good product but your blade promotions specific to this actual product are far too infrequent.

I have used these for a long time but have experienced quality problems. The top blade has a tendency to ripple and cause damage to my face when shaving!
