Great little portable vacuum cleaner. I gave it 4 stars because the suction power isn't amazing, but for a small $25 machine it's pretty good. I use it daily for about a week and the battery is fine. Totally worth the money, but if you're looking for something with amazing suction power, you might want to consider buying a more reputable brand. I have used it on my car and around my house with 2 dogs. I'm happy with that.
