I've got Sealskinz All Weather gloves. They're supposed to be waterproof, but in reality anything more than a brief shower and the water gets through. They're supposed to be breathable, but in reality if it isn't below zero my hands sweat. They're supposed to be warm, but in reality if it's below a few degrees Celsius my hands get cold.
This is exactly the experience I had with Sealskinz gloves. I had the ones with 'Waterproof' written on the index finger. I think they were these:

Absolutely useless gloves. Not waterproof in the rail AT ALL. I had a funny conversation with another cyclist commuter spotted on the train with the same gloves. Useless, useless things. They also have no reflectives on them either which isn't much help if you are trying to indicate after dark.
I'll be shelling out on expensive ones for this winter. No half measures this time.
