While very simple to pair (it only needs to be done once), actually playing games, specifically online or competitive titles, over Bluetooth can be an exercise in frustration. Still, for what it is, the Razer Raiju Ultimate is easily one of the best PlayStation 4 controllers on the market. You'll be hard-pressed to find something else so brilliantly designed, and the great app support only makes it that much better. For a controller being marketed at esports professionals and hardcore gamers, that’s a huge issue. Thankfully, the two markets generally will always favour a safer wired connection for this reason, so it’s not a complete deal-breaker. It will be a huge annoyance for casual buyers, especially considering the controller’s hefty cost, however. EU Declaration of Conformity for Abyssus Lite & Goliathus Mobile Construct Ed. Bundle (RZ83-0273).pdf

If the controller is forced to enter bootloader mode by pressing the buttons, it will not be able to upgrade the firmware Rounding off the extra inputs, there are basic RGB, profile settings and media keys lining the Ultimate’s bottom. I’m not super fussed about RGB lighting, but on the Raiju it’s useful, as it lets you match profiles to specific colours, so you know which one you’re using at any one time. Unfortunately, you can’t remap inputs like the face buttons or shoulder triggers, only the Multi-Functions, at least at this moment. Additionally, you can see which firmware version your Raiju is running on the app, but you can’t update it (that requires PC access), which feels like a silly oversight. There are some issues using the Raiju wirelessly, however. The Raiju Ultimate features Bluetooth 5.0 wireless connectivity. This should be okay, albeit not as good as proprietary or 2.4GHz connection like the ones seen on the Xbox Elite and Astro C4. But with prolonged gaming sessions, I regularly saw latency creep in. It targets the same hardcore market as the Xbox Elite Wireless Controller Series 2 and Astro C40 and is being marketed as the ultimate weapon for budding esports athletes and hardcore PS4 competitive gamers.The changes you make with the app are immediate, and you should see no delay when switching profiles or even testing out which Chroma lighting you prefer. Should you decide to lower the vibration motors on either side, the controller will vibrate automatically afterward so that you can feel exactly how it was changed. Conclusion

The paddles’ large size is a minor annoyance as it’s all too easy to press them accidentally during heated online sessions. But for the most part, the extra inputs are useful, especially in genres like ARPGs, MOBAs and shooters. The inclusion of switches to lower the regular triggers actuation point is particularly great for the latter. If it were possible to ignore the pesky wireless Bluetooth (and occasional wired) lag, the Raiju Ultimate could have become one of the best PS4 and PC controllers on the market. Hopefully Razer can iron out its firmware issues and realize the Ultimate’s full potential, but until that point, you might want to look elsewhere for your pro-quality PS4 controller needs. The system is about as intuitive as you’ll find. My only minor quibble is that you can only remap the M-buttons, not the regular controls. Though this is fairly common on most esports controllers. The only other controller I’ve seen do this well is Valve’s Steam controller, which comes with its own set of issues. Connectivity and performance – Wired performance is excellent, but latency creeps in on Bluetooth Then again, at that point, you might as well just save some money and buy the feature-lite Raiju TE, or perhaps the more wirelessly competent SCUF Vantage.
