One of the really great things about this gadget is that it is so easy to pan back and forth with.
This stabilizer will almost entirely eliminate vertical shake, and the added stability greatly reduces horizontal shake. For medium shutter speeds you'll notice a big improvement in image quality. It will also make your videos look a lot better.
This obviously does not make your tripod totally useless. It really isn't going to work for long exposure times, though it would certainly help. It is also maybe not the kind of thing that you want to use with a big heavy lens for long periods of time. That might get a little heavy. This is, however, a great solution for a huge number situations where you might need to use only medium or faster shutter speeds and for times when you just really don't want to bother with a tripod.
You can easily pack one in your camera bag. Then you'll always be ready when the need arises. Try that with your tripod.
