I bought mine a while back off Amazon and they also came with an 80g spacebar switch! Nice little addition. The diffuser helps tremendously on south facing boards where the LEDs can be potentially a little blinding. I was little shocked how bright the LEDS were on my Keychron Q7, which is what lead to getting these.

The factory lube was great out of the box (jar), but have now been developing a little noise on a few. Will likely have to lube them after all. But still, very pleased with them.
