This is an update to my previous review. While I do like the feel and the sound of the switches, I have noticed that they are symmetrical, north to south. In other words, I have noticed that they cause interference with cherry profile switches regardless if the switch is north facing or south facing.
This is primarily noticeable on the "ASD" row of keys. The other rows seems to have just enough clearance as to not cause an unpleasant sound when typing.
The Keycaps I have tried are: Akko cherry profile PBT, GMK Hammerhead, and PBTFans Doubleshot Spark.
All of them caused interference with the switch north facing or south facing.
This doesn't change my impressions from my first review, and the are especially smooth once you lube them.
They lose one start due to interference.

Novel and interesting, but also quite good. A switch for switch nerds - and lovers of kawaii.

Softer plastic on the bottom-out, harder plastic on the top-out, and a little heart in-between the stem halves. Cute *and* smooth.

Initial Impressions.

Build Quality - These seem to be built very well, there is literally no movement between the top and bottom housing. In fact I tried to film them, but didn't have a lot of luck snapping the housings back together again as the film caused too the small latches to not catch properly.

There is very little stem wobble, especially compared to my reds, but I don't have many points of reference.

The unique construction of the switch gives them a very different sound from my cherry reds. My reds are filmed and lubed. The overall sound of an unmodded switch sounds very nice with a nice low (dare I say) thocc. They seem to have a bit of a pop on the return. Overall it is a very pleasant sound when typing.

Smoothness - These are very smooth switches and there is very little scratch, but you can detect some when you hold it to your ear. It was really hard to tell, but the stem had a bit of a shine on it and that may be factory lube?? It was very light but I couldn't tell anywhere else.

I cannot feel any scratchiness in my untrained hand.

There is no spring ping that I can hear.
The physical profile is very symmetrical north to south, they don't have that characteristic bulge where the metal contact/leaf reside in the switch.

The upper housing does seem to have a lens to help capture the light from that sweet sweet RGB, it is a clear piece of material that passes through the lower housing to the top face of the upper housing. Overall my switches look great on my north facing keyboard.

overall, very good switches!
