I have Multiple Sclerosis and besides the Dyson name, I needed a vacuum with a power on/off button opposed to a trigger. I've never owned a Dyson of my own, but my mom has had several. This is my first Dyson and I'm absolutely in love! The suction is powerful yet quiet, it keeps up with dirt/ dust/ particle count, has a countdown timer, and comes with 2 rechargeable batteries!..... plus the on/off button helps with my muscle cramps and spasms. I've been impressed with others', but having my own and being able to use it as much as a like, I'm blown away. I actually enjoy vacuuming now!
