This is an awesome device, but I would hesitate to recommend it at the current price of $100. It can be found for much cheaper elsewhere. At $70, for instance, this is easily a five-star device. **Form Factor** It feels similar to a PSP/PS Vita, which is a good thing. I've used it for upwards of an hour without any discomfort. I'd characterize this device as "pocketable" – it's small enough to fit in most of my pockets anyway. **Controls** The D-pad, joysticks and buttons are all on the smaller side. The biggest flaw is probably the joysticks, which are small, recessed, and not super accurate. Usually they are sufficient, but I've run into occasional issues when precision is needed, like some parts of Mario 64. All the buttons are clicky. This is not a quiet device to use at night, if you're trying not to disturb your partner in bed. **User interface** TrimUI is not anything fancy, but it works well for navigating through different games. It offers pretty seamless save and load states on top of RetroArch. You're basically limited to the emulators that come with RetroArch. The function key is a nice feature that you can program for different purposes. Oddly, I have to use this key for muting the device, as turning the volume all the way down does not take it down to zero. **Performance** I've found that this is powerful enough to run platforms up to N64 pretty well. Several of the included N64 games didn't work though. PSP performance is very hit or miss. Playing God of War, for instance, things can get very choppy, even at 1x resolution. **Screen** This is probably the standout feature of the device. The screen is bright, crisp and big (for the form factor). I like that the older games come preconfigured with themed bezels, so the whole screen is used. Read more
