Im actually really excited to review this. If you look this device up on google your going to find a lot of positive feedback. Its definiteltly a good quality device. The buttons are nice and have a similar feel to a playstation controller; ie silicone rubber, and good button resistance when pressed. There are litterally thousands of games on the SD card, and you can even get your own roms to add.The only downside is that there are a lot of games in japanese but definitely has a lot more in english. They also named every game file in numerical order. Ie: 003 Pokemon Yellow Version.gb etc etc. because of that when you go to scrape the games, it wont work. You litterally have to delete those numbers individually from every single game file to get good results from the scrape. *facepalm* it took hours.In terms of kid friendliness theres definitely adult games on here so youll want to find and delete them. Again theres thousands of games to go through. Youll definitely need to do some work to get this working well for a 5, 6, or 7 year old but you can get it there by switching to AmberElec and only selecting systems to play that work well, limiting the amount of available games for them etc. Basically NDS is garbage and psp, dreamcast will lag a lot so id just not even bother having those on there for them.All in all, Im glad I got it and would highly recommend. Theres plenty of youtube videos on this so check them out!
