The Razer Kishi Mobile has clickable analog thumb sticks for great accuracy and tactile feedback: refined your aim and execution with a familiar Console Controller experience, supported by an array of face and Bumper Buttons, as well as a d-pad for extra inputs. Latency-free game play for smooth control: unlike wireless Bluetooth controllers which produce lag, this Controller has Zero latency because it connects directly to your device’s charging port-which means instant button response. USB-C charging port to charge your device while in use: if your phone or tablet is running low while you’re gaming with the Controller still attached, simply hook up a charging cable to the Controller itself to get the device charging. Making it easy to keep your device charged up while you play some games.  Ergonomic design for a comfortable handheld grip: Designed for long gaming sessions, the Controller feels great to hold and has optimized button placements to make sure each button press feels natural and intuitive. In our review of the Razer Kishi Mobile, we essentially said that this is the best compact mobile controller on the market. And we stand by that. Many of the other options out there are just not good. With bad latency, or bad buttons in general.
