Great Concept, decent execution
I got these in Purple (UHMWPE), the packaging was neat but I feel that you spent too much for a switch that was quite mediocre. If you get purple housings with pink stems with some tx springs, it comes to around 70-80 cents per switch which in my opinion should be lowered to around 50 cents per switch. Honestly, you're better off buying some other switches that you find good reviews on, or a switch that you personally like.
The UHMWPE tops sound really good on Oil Kings and Minks (Ink bases). I also have a set of switches with these UHMWPE Top/Bottoms and Gateron Stems and they sound amazing in my KBD67 Lite. Overall, I would say they're still a bit pricey for what you're getting, but if you are looking for some pretty nice tops for frankenswitching, they're a good option.
