I love it. I wouldn't say it blitzs all the other SE's but it certainly brings a very strong game. Efficient without being too aggressive, dextrous, intuitive (though I did have an initial learning curve) and looks the goods. Hearing initial reports prior to purchase it sounded like it would be on the mild side so I assumed I would be using Feather Pro Supers in it but I find Kai Captain Mild blades work very well. The Colonial General and the Vector are currently my top two AC blade type razors.
I have not heard of anyone reporting problems with the flat sided threaded post on the Vector but only time will tell how that will serve long term. I feel it needs to be looked after from that respect but that design also facilitated the compact head which makes it unique as an SE AC razor, so worth it.
