I have used this for a few years and it has performed flawlessly, there is some Velcro on the casing, which also has a small crack, but this does not affect performance.
NOTE : When I say it has performed flawlessly , that is up until the latest update by Win 10 where it has become a bit problematic and unless you are a computer guru, which I am not , and if you are using the latest version of Win 10, I would not recommend it.
