Depends how you consider "quite well" - the total collapse of Russia's military credbility, the insanely high casualty rate, the loss of material, for something that they were already allowed to use in Crimea, and a part of the Donbas?

I wouldn't call that "well" at all. Seems like a completely disaster.

You're going to have to provide some kind of evidence for what you surely must acknowledge is an absurdly bold claim.
