Comments on HMX Bad Sweetheart switches

The long-awaited Unikeys Purple Dawn switches are finally here! The Purple Dawn switch is one of the earliest HMX switches that use the UPE stem and the first HMX switch that pairs the UPE stem with the P4 bottom housing. If you have tried HMX switches with PA12 or P4 housings, you will notice that the PA12 material is one of the best top housing materials as it is very smooth and comes with a subtle and pleasant top-out sound. The P4 bottom housing is one of my favorites as it comes with a thocky, clacky, and vibrant bottom-out sound profile.
When paired with the modified UPE stem, Purple Dawn switches overall sound quite poppy with a thocky note. They won't be too loud since UPE is one of the more muted materials in this hobby.
Feeling-wise, they are very smooth and come with a clean and solid bottom-out. The modified UPE material is not as soft as UPE from other manufacturers as pure UPE can easily be broken. HMX modified its UPE material to make it more strengthened and more durable – uninkeyboards.com.

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.
