When your Quest 2's left Touch controller goes missing or stops tracking, the easiest fix isn't a brand-new set - it's a single replacement. The listing here is a genuine Meta Oculus Quest 2 left Touch controller, priced at $69.99. It's a pre-owned unit that the description says has been tested and is fully functional.
Meta Quest 2 Left Touch Controller (Pre-Owned)

Quick verdict
If you need a genuine left controller for your Quest 2 and you're comfortable with pre-owned gear, this is a direct, no-frills option. You get just the left controller - no headset, right controller, or charger - so you'll be relying on the Quest 2 equipment you already own. At $69.99, you're paying for a genuine Meta replacement rather than a generic alternative.
Who it suits
This pick makes sense for Quest 2 owners who already have a working headset, right controller, and charging setup, but need to replace only the left Touch controller. If you've damaged, lost, or worn out that left unit, a genuine replacement like this avoids buying a full new pair or a third-party accessory.
What stands out
The controller is listed as a genuine Meta/Oculus Quest 2 left Touch controller with model number LX39EM. The description notes it's in good pre-owned condition with normal signs of previous use and that it has been tested and is fully functional. Connectivity options include USB-C and Bluetooth, and the built-in microphone is listed as a feature. The unit is white and made of plastic. Importantly, the listing clearly states it does not include the headset, right controller, charger, or other accessories - you receive the exact left controller shown in the photos.
Meaningful trade-offs
The biggest trade-off is that you're buying a pre-owned item with normal signs of use, not a brand-new unit. If you prefer brand-new gear, this may not be the right fit. Also, the package is limited: no charger, no right controller, no headset. You'll need to have those already available. The price of $69.99 is for a single left controller, so consider that when weighing it against a full accessory set.
Bottom line
If your Quest 2 is missing only the left Touch controller and you're willing to go pre-owned, this genuine Meta option at $69.99 is a straightforward replacement. Just make sure your headset, right controller, and charging cable are already in place, and note that you'll receive the exact controller shown in the listing.
