      Great toy, bought it as a gift for cousins

      I got this as a gift for my two cousins, aged 14-16, who are interested in programming and video games. They like the system, it's cute, and the piezoelectric sound is a nice touch.

      This is the best tiny console

      Okay so if you are here to play some big games that can rival today's games and be able to see the screen well with all the buttons still working. This is not for you. If you are a person that knows or wants to learn micro python and love little novelties this is the thing for you. I totally loved this thing. (I made rock paper scissors for it!) I didn't have much of an understanding of micro python but was still easily able to get into it. I love the community and all of the help I was given. It really made me want to continue with my project even if it seemed too hard. This is hard to play on though if you ain't a kid. To be honest I actually have no problem playing it and it after a few weeks felt big in my hands. There is one problem u got though but this seems to just be me. I was trying to install a special firmware on it so I could see it in file explorer. It didn't work and I was able to reverse it. But a few days after I saw that the speaker just didn't work. Not sure if it is related but I have a sinking feeling it is. So watch out for that. After all of this it is the best raspberry pi product in my opinion.
