I bought this a month ago to replace my 9 year old V6 Fluffy.  I am very pleased with it, and I am impressed how much cleaner my carpets look, and am horrified when I use the fluffy head with the green light, and see how much dust there is on my hard floors.  I also like that this picks up the grit that the dog brings in.
Overall I am very pleased with it, and I no longer have to keep my finger on the trigger, BUT it is quite heavy compared to my original Dyson V6.
