Discount code "Expel" is 20% on carts over $200, and 30% on carts over $300.

However, depending upon the current sale on the Aim Controllers website, the discount percentage may change.

The current "No Limit" sale allows you to build your own XBOX, PS5, or PS4 controller with as many upgrades as you want, and pay only $209 (plus shipping) with code Expel. This sale ends at the end of March.

Depending upon the current sale on the Aim Controllers website, the discount code may work differently, or not give any additional discount.

This only happens during very large sales. Just use code Expel to give credit for the referral on the controller, please.

If you'd like to go above and beyond the PS5 "Pro Controller," this is what Expel recommends:

• Front Shell Panel: Expel
• Trim: Black
• Action Buttons: Black
• D-Pad: Black
• Share / Options: Red
• Digital Buttons: Yes
• Hall Effects: No - Up to You
• Aim Sticks: Black
• Left Stick: PS Black Small 2mm Taller

• Smart Bumpers: Yes
• Vibration Motors: No(-50g)

While Hall Effects in theory are an awesome advancement in controller technology, Expel does not use them in his personal controller. Nor does he recommend them because of how they work.

Hall Effects are built with magnets that are meant to perfectly align your analog sticks at all times. However, they can easily be misaligned by any outside magnet strong enough to pull the ones in the controller.

This can often happen during shipping, or even with a nearby magnet on your desk or gaming area. Due to this, it can cause multiple issues with your aim, and is not really worth it.

This isn't to say you shouldn't upgrade to a controller with Hall Effects, but just know the downfalls of the technology.

Additionally, they're much more sensitive, requiring you to almost half your normal sensitivity to stay on par with your previous aim.
