○ Quality of the device is god, not perfect and not bad + Compact design + many emulators and games + easy to use + 2 sd kard slots + button combos (powerbutton + vol + or - etc) + very good emulation speed, most games run 60 fps +battery is replaceble - bit laborious to make other games on it (can't send games direct to sd card 1, if you have big sd card 2 there is no problem...) - Sound is to loud on lowest level - (maincriticism) device makes high pitched sound sounds like a power supply, if it is on, maybe a defect or normal? -resetbutton easy to press, (not terrible, makes a good quickstarter) - Stick a bit slippery - Displayglass glue gets off a bit - no use for the button abouth the select button (why) - no stand by mode - no wifi/bluetooth or someting, (no multiplayer) the most negatives are easy tolerable, it's a nice device to play retro games on the go... i like it much :D
