On the second day when I wanted to use the fan, I suddenly had five parts in hand. The small screw is completely fallen out and some plastic I had in hand. Did everything fixed with scotch tape and it works perfectly again. I am really pleased in general makes you beautiful wind and if not exactly dead silence on the work and you can not hear him. What has just wondered which have not lived very long the batteries supplied, best rechargeable use. So who wants to just have some cooling on the go or at work is just right with the product.
