I did a lot of research on Anberic handhelds before deciding to go for this one and I'm glad I did. This thing is a dream. It feels amazing in the hand, controls really well and runs anything I throw at it (from PS1 era downward). I wanted something premium-feeling and this is it. A couple things for would-be buyers:1) For anyone concerned with the manufacturer name shown in the title here like I was, I can confirm this is an authentic Anberic RG351MP device after poking around in it for a while. I think this is just the name of the distributor or something.2) The screen is the reason you want this model over the RG351M or 351P. It's got a beautiful 640x480 display that's viewable even if you have the thing turned completely sideways. You might have to adjust integer scaling for some consoles/roms, but you'll generally be able to find something that looks good.3) Everything PS1 and earlier runs flawlessly though there might be one or two little exceptions as far as PS1 goes. Anything past PS1 should be treated as a bonus because a lot of it runs poorly, but seeing as this is mainly targeting only up to the late 90's for its library that was fine with me. Expect only about 20-50% of N64/Dreamcast/PSP games to run, if they boot at all. Anything from PS2 onward will be a no-go.4) It came with a 64GB card packed with roms which of course is questionable depending on where you live and what your backup collection is like. But I wiped the card anyway and populated it only with my own copies of games/rom hacks and it went smoothly. It's easy to do but you'll need a microsd card reader, so keep that in mind. The card you want to replace roms on is in the TF2 slot on the bottom bevel of the machine.5) Battery life is good but it'll take a while for the gauge to display the battery life correctly, because it needs to drain/charge fully a few times first. In general I think it's got about six hours in it before you need to recharge.All in all it's a great little product and one I'll definitely get a lot of use out of. Hopefully it doesn't spontaneously break or anything. If it doesn't it's an easy 5 stars.
