Review:
Announced at CES 2020 with plenty of hype, the Razer dual-sided iPhone controller (made in partnership with Gamevice) was an ambitious attempt to turn your iPhone into a true portable gaming console. Unlike clip-on controllers, this one wrapped around the phone, giving you a Nintendo Switch-like experience.

Build quality – Razer’s signature black finish, textured grips, and clicky buttons felt premium.
Low latency – Wired Lightning connection meant no Bluetooth lag, great for action games and FPS titles.
Pass-through charging – A Lightning port on the bottom let you charge while playing.
Game compatibility – Worked with MFI-supported games like Call of Duty: Mobile, Grid Autosport, and Oceanhorn.
