Frequently asked
How strong is the Firecracker bump?
Strong. It uses a P-shaped tactile profile with a heavy bump, so the feedback is sharp and pronounced — this is a tactile for people who actually want to feel the tactility.
What is the POK stem about?
POK is a stem material HMX debuted on Firecracker. It contributes to the crisp, high-pitched clack and a slightly different glide than their usual POM stems.
Is the weighting heavy?
The actuation is a light 40g, but the bump and the 58g bottom-out make it feel more substantial in practice. The early light actuation with a heavy bump is a distinctive combination.
