MJKJRG351M Handheld Game Console , Aluminum Alloy Shell 64G TF Card 2500 Classic Games Support WiFi Function Open Source System RK3326 Chip 3.5 Inch IPS Screen (Gray)

First, a few positive words. I liked the overall sturdiness of the device and a lot of configurability of the device. Quality of the display is good, responsiveness to controls is overall great. I liked an option to upload new files via ssh, it saves a ton of time that would be otherwise spent removing SD card, finding SD reader, connecting to the "big" computer and uploading files there. There is also an option to use FTP which is really nice, all of these easy transfer options are thanks to embedded wi-fi.Note, that it does require your wifi router to use 2.4GHz channel and at least for me it didn't see a 5GHz wifi network.Now bad things.The biggest one I couldn't find remedy for is the absence of durable saves. I didn't try all emulators, but tried a few times NES and PSX and still got the same results: save games don't survive power offs and may not survive resets. One "unofficial" advice was to explicitly use "Close Content" option whenever you want to make your save "durable" but it still didn't work for me, at least for this specific model that I bought.The other bad thing which may not be too bad per se is occasional glitches that don't let you turn back on the device once it turned black screen. It still can be resetted but then again, you lose your saves which amplifies the first bad option.I noticed a few glitches while playing PSP games - flickering of graphics, but this can't be attributed to this device and perhaps rather to quality of PSP emulator it uses.To sum it up, I really liked the device, but apparently there is still a lot to be desired on the software side. I'd happily give it a 5 star if there is at least a working solution for game saves that can survive device resets.UPDATE:Another problem that I noticed is that device consistently silently turns off all controls when power level is below some value. Screen is working, audio works, but no device does not respond to key presses. This, plus issues described above and overall seller unresponsiveness is why I downgraded my review to 1 star.Returned back my device.

This is a well built little machine. Controls feel sturdy but not stiff. Analogue sticks also have a nice feel to them. One proper charge will last at least four days for a low to medium gamer. The metal body also feels great in the hands. If I had one wish it would be that it could port via hdmi to a tv or monitor sometimes. Overall great buy.

Everything else is fine!

Product arrived. Looked great. Inserted SD card into device and the device was stuck at the boot up logo. Trash SD card or firmware.
