I've acquired several packs, but I've only used a few blades. My impression is they are not Gillette's finest- Gillette is only mentioned on the package, not the blade and the blade printing is one sided.
They were one or two shave usable for me, but they were not anything special.
By all means try them, but your mileage...you know the rest.
Clearly a case of YMMV here since for me these blades are very very good.
Shaved with one this morning and I'm really wondering whether the 365 is actually a rebranded 7 O'Clock Black at a third of the price.
I know this is a bold claim - the 7OC Black is my favourite blade but these 365s have the same supersmoothness, excellent sharpness and longevity.
