To me this looks like the hand saw which my dad kept in the garage when I was little. In reality though it turns out that this is a handle for your Macbook. It doesn’t look very sturdy and I am not sure many people would be pleased by where the handle is placed before carrying it. This handle fits between the space of your screen and keyboard and then you simply close and carry. The mBrace, as they have named it, does not look like a very safe or sturdy option for carrying around a Macbook. There are simply so many things that can go wrong with this case. The mBrace is meant for the short trips to the library or the coffee store, but it still is not convincing enough for me to try with a Macbook.
