Purchased the Pro grip (Quad) back in July.
Postage was approx 4 business days and I don't live in a capital city which was very reasonable!
I didn't want to rush into a review because I wanted to test the controller on multiple games such as Cyberpunk 2077, It Takes Two and recently released Modern Warfare II. The mechanical face buttons is a must, arguably the most important mod for overall quality and slickness of the controller. I also got the Mechanical triggers which at the time of purchase was the only option however I'm superbly impressed with them. I can't play an FPS without them, a game changer for MW2. I didn't get any of the extra options because I quite enjoy still having the rumble feature as an option I can always toggle off.
The triggers still feel sturdy 4 months later and don't feel worn. The rubber grips are also more than an aesthetic as I really appreciate the way they feel on the back of my fingers. Have NOT experienced any stick drift at this stage in time.
I wouldn't recommend hair triggers if you plan on playing racing games or games that require throttle control unless the haptics can be turned off. For example Cyberpunk 2077 plays great and the shooting is fantastic however I can't hit top speed in a vehicle lol.
Overall paired with some KontrolFreeks I have found this to be the perfect FPS controller. Battery life isn't worse than any given new ps5 controller. No issues with the audio jack or internal microphone or speaker either. I think if this controller could achieve adjustable triggers it would out perform the Dual Sense edge which isn't even released yet.
