We have had our Dyson Gen5 Detect for about a month. Minor assembly was intuitive but the instructions were complete in case we had needed help. All parts were in the box and in good shape. We, like everyone else, were shocked by the extra dirt and debris it picked up. The hair from our cat that it picked up was amazing and our wood floors look better than new. Neither I nor my wife found it heavy. Surprisingly it is very quiet as we were expecting the extra power to result in extra noise. It is so quiet our cat is not afraid of it. Both heads and the attachments work well. BTW, the cat loves the green laser.
