My feedback:
1. It works great. I had to empty it several times because it was picking up so much more stuff than our existing vacuum did - mostly pet hair and the like.
2. It's the one with the little laser thing, which is a dumb little gimmick until you see it in action and then it's life-changing - if you're like me and find satisfaction in picking up every invisible crumb anywhere.
3. After a year and a bit, maybe less, it started misbehaving. It would suddenly turn off, then you'd have to let go of the trigger and pull it again; then it would work fine. Then it would happen a few times until it worked fine. Then it almost never worked fine. I kind of tolerated it for a while until I got fed up and googled the problem, and it was suggested to buy a new housing - the electronics plus the motor, basically the whole 'vacuum' part of the vacuum, which was only just over a hundred dollars direct from Dyson. Irritating to have to spend an extra hundred bucks to get my five hundred dollar vacuum working as expectred, but expected it to cost far more.
Would I recommend it? Not sure. It's very expensive, it works very well; it has a nice wall mount that charges it and which holds a small subset of the attachments it comes with. I'm glad I have it and I use it often.
Yes, it's plastic, but if it were, for example, steel or aluminium then it would be too heavy to use for any length of time. As it is, it feels very sturdy and has held up physically very well, but I'm obviously also not rough with it so there's no reason it would have any issues unless it were, in fact, cheaply or poorly made.
