Works surprisingly well. I bought it for excess condensation in the bathroom and was very easy and effective. It made my shower gleam especially the plastic door which I wasn't expecting. I know people have said about the battery, but it takes less than a couple minutes to do the bathroom and lasted a few days before needing to charge. I think it depends on how you use it. Short bursts and it will last longer between charges. I paid for the extra small blade which was worth it. I do not know about the washer bottle but I could not see the point in it. I do think it's ridiculously overpriced though.
