Frequently asked
Is the HMX Bad Sweetheart a light or heavy switch?
It's on the lighter side. Actuation lands at 45g with a 50g bottom-out, so it's easy to press for long sessions without feeling mushy or floaty.
Does the Bad Sweetheart need lubing?
No. Like most modern HMX switches it ships factory-lubed and feels glassy out of the box. Hand-lubing offers diminishing returns and isn't worth the effort for most builds.
What does the Bad Sweetheart sound like?
Rounded and full-bodied rather than clacky, thanks to the P4 bottom housing. It leans deeper and quieter, pairing well with poron-filled, gasket-mounted boards.
