First of all, this item works well and sucks up crumbs from the car or the floor fairly well. Not powerful enough for the amount of mechs it doesn't pretend to be. It has good jets to get what you need out of the cracks. I like it and I keep it in my car. It comes with a USB charging cable, which is very convenient. The cord isn't very long so you'll need a charger if you need to vacuum. It takes 15 to 20 minutes of vacuuming to charge, but it seems to be pretty quick to top up in an hour or less. works perfectly. I wish there was an easy way to reset the contents, but you have to remove the filter and take it off to get rid of the dirt. This is a minus, and not that the lungs will loosen and go away. At this price it's just normal value in my opinion, but it works as promised.
