PersonnaPersonna Tri Flex Cartridge, 8 Count

Fits like the name brand but at a better price.

The cartridge is designed in such a way that water cannot pass through and clean out the hair between each blade. Vigorous rinsing in water and pounding the razor on the edge of the sink will not clean these so unless you like plugged razors don't bother purchasing.

These blade refills aren't of the same quality of the original Gillette Sensor blades they replace, but they're adequate, and their price per blade is something I can see as reasonable-- and Gillette refill blades have become something so outlandishly expensive that I became determined to never buy them again. I even called them on the telephone once to tell them so. Sensor blade refills have at times reached a retail price of nearly three or four dollars a piece. A pack of them, over forty dollars. You can forget about that. These Personna substitutions fit as if original and use fairly good steel; they don't wear as long, but for the savings, it's a smart move for me. If you're ticked off by the price of Gillette razor blade refills, I do recommend these.

I love these. I mean, they're razor blades. They fit my Sensor handle. And they work. No complaints about quality, and they are cheaper than the brand-name blade cartridges, which are a racket. I feel like I'm sticking it to the man, just a little, whenever I buy these : ) Someday, of course, I'll go all-in and just learn how to use a safety razor. Till then... hooray, Personna!

I wish I could give 5 stars but I can't. These blades are not a direct "click on" fit for the Gillette Sensor handle. Have to work it a bit to get proper engagement. However, once engaged, these value priced blades do provide a smooth close shave with no irritation.
