If the Rubies are indeed similar to the Astra SP, then they are a big no, no for me. The Astra SP isn't that bad, but for me they are right in the middle between good and bad blades. I can get a good shave with them, but they are not as enjoyable as Nacet for instance and i've noticed that they don't last very long as well and the 3rd shave is either painful or impossible.
I could be wrong, but I think the Gillette Rubies are the most expensive Russian blade on the market and even if they are slightly better than Nacet, getting 100 Rubies for the price of 200 Nacets isn't worth it imho, but ymmv, as always.
