As a big Shark/Ninja fan I was a little underwhelmed by this vacuum. It doesn't seem very powerful. I can grab my stick vacuum, pull the vacuum motor off of it and I have something handheld with tons of suction. Then I realized that it's kind of a drag to do all of that to suck the toast crumbs out of my toaster oven. It's really, really hard to wash them all out, but a small handheld vacuum works great. No way I'm going to get the big one for a job like that...that's where this machine fills a niche. So, I do honestly think it's a decent handheld. It charges fairly quickly and holds a charge. The absolute best design feature though is that it's got SHARK embossed on the transformer/adapter cord. No getting that mixed up. That's an amazing step forward. I'm always losing/mixing up my charging cords. 

I think it could be a little more powerful, but it's also as good or better than other brands I've owned.
