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.
these are great as far as quality but I was disappointed to find out that you have to use them with the MM switch bottom housing because it has some legs near the leaf area that prevent it from closing on other switch bottoms
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.
