I tend to shy away from a small controller. I don't have especially large hands but as I age I much prefer something with good ergonomics. Although this one is indeed very compact (see photo for comparison to others), it does work surprisingly well and without too much fatigue.
Visual Style: I think the look is great. Honestly, that is the main reason I picked it up. Very cool aesthetic overall. Even the glowing status buttons below kind of look like they are part of the motif.
Build Quality: Very good. The metal back is sturdy and feels nice to hold in the way that it is geometrically rounded outward. The buttons themselves have a good response not dissimilar to a switch joycon. The joysticks are reminiscent as well, with a good amount of travel without being too slim. The big variance is that both shoulder buttons are mounted inline. This might be a bit cumbersome depending on the game, but in my experience I was able to navigate this change in orientation without much issue.
Rumble Grumble: I don't care for tiny rumbles in controllers and this one isn't much different. It works in that it makes a buzz when prompted but doesn't communicate much nuance. I was not unable to get the settings to adjust according to the manual (should be 4 levels) so it felt pretty harsh. If I could tone it down (maybe a firmware issue?) that might solve the issue for me. Truth be told, on a controller like this, I would just as soon turn it off altogether.
Connectivity: This works well across the board. I have used it with an iPhone, iPad, AppleTV, FireTV, PC, Switch, and a Steam Deck. Suffice to say, it works as intended on all devices with the exception of rumble not functioning on the IOS devices for some reason. The pairing process is easy enough just make sure to properly press the right combination of the pairing button, and the face button. The instructions do a good job of detailing how to appropriate pair depending on device type.
Inputs: So far, I haven't encountered any notable drift of phantom inputs. I would prefer a more traditional D-Pad but I also won't penalize them for that choice. As a D-PAD for menus and basic navigation, this one works just fine.
Firmware Updates: Haven't had to do this yet but I did take a gander at the firmware update app on IOS. It very seamlessly detected my controller and checked for new firmware. Nice to know that if there are any issues, an update won't be hard to come by.
Turbo Function: I tested turning this on, and it works. Kind of cumbersome to deactivate (see the manual). Personally, I have no use for it but if you do, it's there.
Accessories: Comes with a nice little semi-hard shell carrying case, a USB-C cable for charging and connectivity, and a pretty good little manual.
Long story slightly longer: This is actually a pretty decent little controller. Well build, portable, versatile, and stylish. If I ended up having to use it as a last resort for a round of mario kart, I wouldn't be upset. And, for the level of build quality, I think the value isn't too bad either (about $33 as of this review).
