Good option if you have a room that doesn't get enough airflow. Wish I had this as a kid.

I speak from experience, sometimes you can't get the pressure you're looking for at the end of a house with a one zone setup, regardless of what you do with duct run sizing. These vent fans will help a little, especially with cooling.
😂 some of us northerners actually have something that's called a finished basement. These so called basements can sometimes feature recreational areas, bars, bedrooms, home theaters, walk outs, and real windows. Even after all that cool stuff, we can still cram our mechanical areas in there. The mechanical areas that house our furnaces, hot water heaters, water softeners, electrical panels, ductwork, and plumbing.
The basement Is a wonderful concept, you can basically work on any mechanical system in your house standing upright, or on a ladder in your basement. Not a slab, not a crawl space, not in a hot attic, and not working on your back in dirt, or having to excavate plumbing problems in a slab, it's a basement it's fantastic.
Finished basements are wonderful. But evidently I should be trading my finished basement and floor vents in, so I can be a cool guy like 99% of the world that has ceiling vents. 😂

Another case is my brother-in-law whose home office is in a small room that he has to keep closed much of the time while in meetings to keep the sound of the wife/kid/dog out. When closed up in that small space, his computer equipment alone is enough to heat the room fairly quickly.
Having said that, don't expect miracles. These things help, but they can't create airflow that isn't there. Also, they generate a bit of noise on higher settings. Kind of a white noise and not unpleasant, but just know that it's there.
My basement duct is at the far end of the house from the furnace, and it's shared with the bathroom above so the basement gets pretty weak airflow.
One of these completely solved the problem. It just equalized the airflow between the two rooms. The thermostat is easy to set up. Haven't had to touch it since the day I put it in.
If you don't plan on using it for months on end, unplug it. It's not rocket science.
Needs to be a niche use case. I have one room that's at the end and it doesn't get the same air blow as registers in room before it (blame lower tonnage or poor routing or whatever), so this helps "suck up" and "steal" some of the flow for the register at the end, to help compensate.
But yes, it does not generate anything more than that.
