Overall a good purchase. I didn't buy it for a very typical use case I don't think - I bought it to help me clean my gecko's terrarium of dirt. It does its job fairly well, but there are a few downsides here: The battery is small, but that makes it cheap and light. The suction power isn't very strong, but it's good enough to ensure that the battery lasts as long as possible. The filters supplied seem to get clogged very quickly, but they do a good job of protecting the inside of the vacuum cleaner from small impurities. Good thing they include multiple filters because after almost every use I have to take the filter out and clean it. I'm not sure how long each filter will last, but I've cleaned them a few times so far and they're still working fine. Almost no air comes out of the back of the device. But once you install a new or clean filter, suction power is decent again. I would recommend it for light work - great for picking up crumbs or small debris. I wouldn't recommend it for picking up things like powders as it clogs the filter very quickly. Also keep in mind that you'll need to charge it after a few minutes of use, or at least for as long as I get between charges.
