The ones from Haircare & Beauty are the real deal... and it's a Spectacular deal for 3 pucks, I paid ~$52.00 for three four months ago, and I consider that to be a bargain for a quality shave soap.
I like it a lot. The scent is a little different than most sandalwoods, with a hint of sweetness and vanilla. It doesn't smell much like the AoS sandalwood, although I think it complements it nicely.
All Stirling splashes have liberal amounts of aloe, glycerin and hydrovance, so even though they're alcohol-based they leave your skin feeling conditioned, almost like a balm.
