The Good: Plush and fluid all the way through its travel. Zero catch when suspension is first activated. The mid stroke doesn't blow through its travel. This also enhanced its pedalling abilities. I had the elka stage five before, but it would stick when first engaging and it blew through the travel too easily for my liking. The Vector fixed all the dislikes I had with my previous shocks. The bottom out is controlled, giving it a bottomless feeling. The adjustments do what with are designed for.
The Bad: Depending on your preferences in riding there could be one thing that you might not like- or you may like it if it suits your riding style. The last part of the rebound before it returnes to length slows down. It doesn't give you a pop off the lip of a jump. But at the same time it won't buck you if you come off a lip off balance. I think this charactistic adds to the constant fliud feel. Going fast through big rocks I think it gives smoother control. Adjusting the rebound changes it but doesn't make it go completely away.
This shock does what it was designed for. I think it works as well as the best rear shocks out there and better in some ways. I am very impressed so far. The lower cost in this case dosen't mean less.
