I was recommended this product from 2 friends at work as they had both ben amazed at this gadget, and they knew I had a lot of windows in my house (glass in doors, 2 sets of French doors and a conservatory) - but I didn't think it would be worth the money. But after doing a bit of internet research I decided to buy the set with the additional extras from Amazon as it was the best price... and I've never had so much fun cleaning my windows!!! It is fast, easy and very addictive. The only problem now is that my kids keep dirtying my windows, so I've got a bit obsessive about having them lovely & clean, but as it's easy and quick to use, I don't mind doing them now. You will still need a soft cloth to wipe over the edges of the windows as the rubber blade doesn't always fit into the edges, but overall it's a great tool to have, and if you are thinking of getting one, I would recommend you get the kit with the small blade as it's better value for money.
