It certainly is unbreakable!
Have had this product for over a year and it has proved to be unbreakable so far. It is quite small, but this makes it very convinient to keep on your person. There are a few faint scratches on the surface now but not enough to cause any problems - you can still see in it perfectly fine. Overall this is a handy little product!
Pros: Unbreakable!, Very light and portable
Cons: Few small scratches on surface
Would recommend: Yes
