I take this handheld to work everyday and play on it at lunch time or when I just have time to kill. It's comfortable to hold, has good sound, has a good looking screen, and has good face buttons/d-pad/shoulder buttons. The few downsides are that the screen is a bit smaller than I would like, It would also be nice if it could get a little brighter (It is a little dim when I'm sitting in a car and the sun is shining through the window). The OS that it ships with isn't the greatest but that's an easy fix, I run Adam on mine. Overall it is a good quality device.

I have tried already the 45$ one and the RG350M.
Anyone trying to decide between the two because of the prices, my advice: Do not even hesitate and get this second one.
The experience is amazing. Everything feels very good about it: Weight, screen size, controls, material, fps, battery ...
I couldn't be more satisfied.

Build quality & IPS screen is fantastic, but customer service sucks. 4 out of 5 of my orders were perfect, but if you're unlucky and it arrives with an issue... don't expect any help.

Great little device. After short setup (there are loads of tutorials online, if you are not sure)you can get your hands on hundreds of games in very covenient package.
Love the open-source concept. As a bonus, the 350M is built like a tank. Package arrived within a week from placing the order, so no problems there as well(within EU).

I absolutely love my console! So many nostalgic games ! Easy and customizable configurations. A must have for any gamer
