I have been using this product for almost a month now, this is a fine laptop sleeve, easy to hold keeps ur laptop away from unwanted dust, also acts as a good surface for mouse movement due to its broad area, comes handy while gaming plus stitching of the product is good as well. Dont know about the waterproof thing as i didnt test it with water but overall it is a good product and you can go for it. And there remains ample space even after putting your 15 inch laptop inside. Overall its a value for money!! Thank you.
