HMX is a relatively new switch manufacturer that is known for excellent factory lubrication. The HMX Poro switch is unique in its housing materials, and has been pre-lubed consistently with a mix of Krytox 105 and Krytox 205g0.

Material-wise, Poro switches are similar to the Swift switches. You can consider them to be a re-color. Although they have different bottom housing materials, I doubt that is going to make a huge difference. However, Poro switches do have a shorter travel than the Swift switches. Please choose between these two according to your own preference.
