Great Items
They are perfect for me, they are stiff could be stiffer but I might not enjoy it being a little more stiff but so far they've helped me alot with aiming at a much faster speed they have no issues and work great just like having oems that are much better I Definitely love them would recommend to anyone else

Astro C40 TR Tension Module
I’ve been using these controller thumbsticks, and I have to say, they are absolutely excellent! The responsiveness and precision are top-notch, making my gaming experience much more enjoyable. They feel solid and comfortable, even during long gaming sessions. I highly recommend them to anyone looking for an upgrade. Truly a great addition to the controller
