The product does not meet my expectations at all. Here are the pros and cons: Pros: He did his job! It cleaned my car and wasn't difficult to use. Since it has to be plugged into the car, I also don't have to charge it before using it, which I think is very convenient since almost everything has to be charged these days. Cons: Cons: Basically nothing. to do with its function but it affected my user experience. First, a lot more space is needed to store that vacuum. My previous one is much smaller than this one. Second, it's very, very noisy. I might use earplugs next time as the noise bothered me a lot.
