To my surprise, every double pedal cobra in bentley (new or old model) are all sold out.
I got em' from Deadeye Guitar, I'd totally recommend to get your gears from him. His price is good and he is super friendly.
As much as I wished to use the stock beater came together with the cobra, I get 2 extra hard rubber beater to prevent damage to my E-drum.
Setup is a little weird for my position of my pedals because space

, but I am fine with that so yeah

As for the pedal, here's my thought:
At first I wasn't used at all, it is definitely heavier than my old pedal that came together with Roland (double-chain drive).
But once I am adapted with the pedal, I gained so much control and power compared to the last pedal I've used. Although I get fatigue a little bit faster (well it is also contributed from my injury from the car accident few months ago).
Here's the pictures
