So far by my testing these seem to be the best budget ESC. They are handling noise very very good (Double very so I trully beleive these are the best bang for your buck as of all my testing so dar) and the motor sounded a lot smoother than others i have tested in the same price point.
These will reduce noise and blackouts in your quad without a LOW ESR Capacitor witch in my book is a no brainier.
I will be buying more myself for use and replacing on other quads that I have built.

I highly recommend checking their products out on their websites to get the full spec sheet.
