This is a nice little vacuum cleaner. I bought it to keep on my desktop. It does exactly what I need. Battery life hasn't been a problem so far. I did the initial top up on November 4th and haven't needed a top up since. I really like the charging indicator on the adapter, which changes color from red to green when the vacuum cleaner is fully charged. The dirt tank is decent, so I don't think I'll need to empty it often. I was looking for something more than the small keyboard vacuum I used and the full size vacuum. It seemed to fill the bill. Then again, this is a pretty weird spherical shape. It looks like a black cone. The base on which the vacuum cleaner is placed is not intended to store the accessories supplied with the vacuum cleaner. Also, you need to hold the base with one hand while pulling out the vacuum with the other hand. Overall, I would recommend it to anyone looking for a similar purpose.
