This controller arrived right before mobile gaming exploded with controller support (e.g., Genshin Impact , Call of Duty: Mobile tournaments). Unfortunately, the rise of Bluetooth controllers like the Backbone One and Razer’s own Kishi (released later in 2020) made this dual-sided model obsolete quickly. The wired connection was great for latency, but the lack of telescoping flexibility (it didn’t stretch for cases or different phone sizes) hurt its longevity.
A major pain point for Lightning iPhone owners is charging while playing. The Razer/Gamevice unit includes a on the bottom left grip. More impressively, it retains a 3.5mm headphone jack—a feature Apple abandoned years ago—specifically for low-latency audio monitoring.
The Kishi represented a complete overhaul of this concept. Instead of modular halves, it adopted a rigid, dual-sided design where the two controller grips were permanently connected by a flexible, expandable bridge. This bridge could stretch to accommodate a wide range of phones, from the iPhone 6 all the way up to the then-new iPhone 11 Pro Max. Most importantly, Razer abandoned Bluetooth in favor of a direct wired connection. The Kishi used a hidden, flexible Lightning connector (for the iOS version) that plugged directly into the phone's port, effectively turning the device into a first-party accessory. This shift to a wired connection all but eliminated input lag and, as an added benefit, meant the Kishi did not require its own battery, drawing power directly from the iPhone instead. This solved the two biggest problems of the Junglecat: compatibility and latency.
