Well, I tried my dollar store Assured razor and blades tonight. But not together. Too risky.
My SuperSpeed had a twice-used PPI Gillette Platinum, a combination I can count on to not give me trouble though I get better shaves with my Slim set on 6. I took the GP blade out and installed it in the $1 razor, and a new Assured blade into the Super Speed.
Showered, lathered, grabbed the Assured razor and shaved my right cheek WTG. It cut okay, but red bumpy irritation everywhere.
Put it down. Grabbed the SS with the Assured blade and shaved my left cheek WTG. It also cut okay, but red bumpy irritation everywhere.
To hell with this. Swapped the GP back into the SS and finished shaving with no further issues. First time ever that my cheeks are more irritated than my neck. Had to use the after shave gel instead of the splash today.
The Assured razor and all four unused blades to the trash, the used Assured blade to the sharps box.
It wasn't money wasted. I got a valuable education for just one dollar.
To each his/her own. The Assured Razor and blade combination shaved as good as my Paradigm 17-4 and my other higher-end razors. I couldn't say that of other cheap razors I have owned or tried. YMMV indeed.
