Very handy we've just got one

cost £40 from Dyson
At £40 it does seem to be a bit over-priced, but knowing the quality of Dyson stuff, I'd expect 'you get what you pay for'...
It works on the principle of attaching the tool to the hose of the particular Dyson you happen to have, and then holding the nicely ergonomic Groom Tool, pressing your thumb on the retractable handle (on the top) that thus exposes the brush-bristles - once a few strokes of the tool have gripped the excess 'fur' you release the retractable handle which clears/pushes the brush-bristles and sucks the fluff straight down the hose - rinse & repeat....voila!
So far we haven't had one bit of mess, and Brogans coat looks great. It doesn't bother him at all, and it even seemed to have a fairly soporific effect on him
Out of 10, I'd give it an overall 8! It misses the last 2 simply on the fact of cost. Was it, say, £25, I'd give a 10/10. However, it does come with free P&P and was delivered in a few days, so no long waits.
All-in-all, if you do have a Dyson, it's deffo useful and worthwhile investing in if your four-legged friend(s) does have problems with "fur, fur & more fur". I think over the years it'd prove more than worth it's money
Hope that helps, any Q's ask away...

I use it every 3-4 days on Brogan and have greatly reduced the tumble-fur around the house
