I think any person can put an answer in Q&A at amazon, what makes you think that the person that answered that question is a CM rep ?
Anyway, it would be cool if you could tell me how does the stablizers feel on your QFR-i.
Oh, I thought he is one of CM rep. He sounds quite certainly. You're right, we should just ignore that factor.
Anyway, if we can consider all Chinese manufacturers who produce led TKL and standard R1, likely it will lead to Vortex, Ducky Zero, Plum and perhaps Costar etc.
So we can at least assume Quick Fire Rapid-I is CST-87-TENKEYLESS until someone prove otherwise because the looks and the keycap OEM similar to Rapid and according to this
http://deskthority.net/wiki/Costar "Costar is alleged to not be a manufacturer; rather, they have been described as a middle-man between their customers and their manufacturers.[1]"
Regarding the stabilizers feel, I feel it is similar like Ducky Shine 3 because they are both Cherry Plate mounted stabilizers. Comparing between Ducky Shine 3 TKL and Rapid-I, I would prefer Ducky Shine 3 TKL because of it build quality to be honest, it's rock and solid but indeed, the price of Ducky Shine 3 TKL is more expensive.
