Review on Bionik Quickshot - PS4 Trigger Stop Lock System for DualShock 4 Wireless Controllers, Black, B0797948Z6 by Marcus Zimmerly

Comes with 2 pairs and I've used them on both my controllers (Gen1 and Gen2/Pro) and they work exactly as intended, no ribbon required. The buttons are not activated, there are no jams and jams. And yes, they are a trigger! The trigger is about 20% down, which means it has to move less. This had no impact on games that use the variable analog trigger feature. I don't know why the reviews are bad - my guess is that people aren't properly maintaining their controllers and their triggers are already active and/or they don't know how to follow instructions. This is the perfect product.
