This product does exactly what it was intended to do. It sucks up dust, dirt, and minor debris; and it does it well. The balance is perfect in your hand; the snout is fairly long for getting into tight places, it has powerful suction, the battery lasts long, the charger is first class and lets you know when it is done, the battery indicator lets you know how much longer you can use the vac before recharge, and it has a built-in brush. That merits 5 stars.
There are two minor cons that don't measure up to the 5-star level. When the brush is rotated and slid/snapped out into working position, it does not stayed extended out if you push hard on the surface being vacuumed. But, I don't think the designers intended that you use the brush to vacuum a carpet. It does work very well on computer keyboards, my cordless phone charging station, the back of my computer, and the nooks and crannies on my car dashboard. What I now do is to wrap a wide rubber band around the extended nozzle, just behind the brush. That works perfectly. The brush does not slide back from operating position, and I can do my whole car very successfully with no brush problems.
The second con is that when emptying the vac, the cannister rotates stiffly, so I hold the handle between my knees and use both hands to rotate the cannister to remove it. I suspect that after I empty the vac a number of times it will start to loosen a little, and it will be a one-hand job.
Every time I use this vacuum cleaner, the thought goes through my mind that Hoover must have assigned their most experienced product engineer to design it. The switch is in the perfect position. The perfect balance makes the unit feel light. The nozzle end just wants to hang down to the right position where you will be cleaning. You can see how much you have sucked up and when it is time to empty. The more expensive lithium ion battery charges quickly and does a lot of cleaning before becoming discharged.
If you can afford it, buy. You will not be disappointed.
