CRC, ya' done got too 'spensive!
I've been using CRC MAF cleaner for years, but they've gotten a little proud of the price, so I decided to give this stuff a try. Honestly, seems to work exactly the same for less money. It cleans well and evaporates quickly. I've not had any error codes using it, so all things considered, this product is a better value than ol' standby.

MY SWITCH AND VR CONTROLLERS ARE FIXED!!!
If you're like me and were at your wits end with stick drift in your nintendo switch, vr or other console controllers, THIS PRODUCT IS A MIRACLE!I tried everything from air duster to isopropyl with no luck. I thought I'd have to buy new controllers until I watched a video that recommended this product. Not wanting to spend another 60-100 dollars on new controllers, I finally decided to spend the 8 bucks on this and used it on both my Oculus Quest and Nintendo Switch controllers which were both riddled with awful stick drift and...JUST LIKE THAT! I havent had an issue since and its been 3 days. I'm so happy I found such an affordable and reliable solution!
