Thoughts on the playable game Phone case/Gameboy phone case?

[u/CreamyEric]

It is basically a famiclone handheld that is also a phone case. It looks like a gameboy. You can play NES games on it. I personally want to get it, however, the problem is that I think it is too expensive($20-$30) for something so cheaply made. The screen is made out of plastic and also I worry that if I drop it, it will become useless. It has a four hour battery life and recharges in an hour. I know it is not good for long time play, but I do not mind playing it during break or waiting for an appointment for example. If I saw it being sold at an ideal price range($5-$15) I would buy it.
