Comments on HMX Bad Sweetheart switches
The Bad Sweetheart switch designed by Rena Lab is one of the deepest sounding HMX switches so far; Thanks to the T5 UPE blend stem, the spherical stem tip, and the new P4 bottom housing molding, they don't sound like your usual HMX type. The new P4 bottom housing comes with as less fiberglass as possible in order to eliminate the clacky tone from the sound profile. If you are a fan of deep and thocky sounding switches that are not muted, the Bad Sweetheart switches would be a great option – Unikeys.
