I picked up the GameSir X5 Lite from Best Buy this week, first impression: it's a bit of a mixed bag.
To start, the iPad doesn't even recognize it out of the box. It took a while to realize it ships in "Android mode", and tiny print in the manual reveals it has to be changed to "Switch mode" to work on iOS. Hold down "select" and "start" buttons for 5 seconds, GameSir logo button goes from blue to red, and then the iPad will see it.
The good part of the X5 Lite is the device fit, it feels like the exterior design is a perfect match for the iPad Mini 6. It wraps around the iPad easily, and it avoids smashing any of the iPad's buttons when it's clamped on. Unlike their Galileo G8 (modded) which is way more precarious to get on or off, and it hits the iPad's volume button when clamped on, needing additional modding of the clamp pads to work around it.
What's disappointing are the X5 Lite's controls. The Galileo G8's buttons and grips are close to a full size console controller and are comfortable to use for a while. But the X5 Lite's buttons and grips are much smaller and closer together. Compared to the similar sized Backbone One controller (I have lightning 1st gen) the X5's controls are about the same size, but on the X5 they are a little closer together than Backbone's. It feels cramped.
The Backbone's grips are taller and flatter than the X5, but the X5 is thicker and bulbs out more in back. The Backbone and the G8 rest more naturally in my palms, but the X5 doesn't find a natural place to sit. I haven't figured out a very comfortable way to hold it.
The other problem with the controls - in Switch mode on iPad, there is no "home" button. (Like the PS or Xbox buttons on those consoles, or the Switch's home button.) None of the X5 Lite's buttons will bring up the Apple Game Center menu for example, and I don't see any way in iPadOS Game Controller settings to remap anything to that function.
Same story in the PS Remote Play app, on the Galileo G8 the GameSir button acts as the PS button. But on the X5 the GameSir button does nothing. The only way to bring up the PS button's menu is to tap the on-screen PS button icon. (At least the X5 works in PS Remote Play at all.)
Playing a game in the Delta emulator, likewise there isn't an extra "Menu" button on the X5 Lite that will open up the Delta menu rather than the emulated game's menus. But at least in Delta if there is a button that's not used for a particular console, you can remap it to the Menu button.
That last Menu button flaw feels like it could be fixed in firmware, if GameSir cared to... a big "if." Of course the GameSir iPad app doesn't recognize the X5 Lite controller, or list it as a supported model, so a hypothetical firmware update might have to be done on another device.
The poor ergonomics and the lack of Menu button might be forgivable since the price is less than half of the Galileo G8 or Backbone One. But at least now you'll be warned. Not sure yet if I'll be taking mine back to Best Buy.
Looks like that Abxylute S9 is probably still the best option under $100. $66 right now on Amazon or
$69 direct.
(EDIT: I decided to return the uncomfortable X5 Lite and order the Abxylute S9 instead. If it works out then I'll probably sell the Galileo G8 too.)
