I use them all the time. They work fine. They're not the greatest but they are locally available and cheap. I can get 4-5 good shaves w/ a blade. I have other blades to try but have so many Wilkinsons I just use them regularly.
Thanks for the heads-up! I have seen similarly packaged blades locally that are store-branded, but now I suspect they may be Personnas as well after looking at those packages.
Personnas work well for me in my Merkur slant. Derby and Wal Mart Wilkinson Sword blades work well for me in all my DE razors.
I've been back to the Wally World Wilkinsons. I can get an OK shave from them. They seem pretty mild. Milder than Dorco ST-300's. Somehow I still manage to get some nicks though. It's like I get a mild blade with the roughness of a Derby...the best of both worlds. I'd use them in a pinch, like if you were traveling and didn't have any blades, but I don't think they'll go back in my EJ DE87 anytime soon.
