Sonitus Acoustics The Kicker 2.0 22"x18" Pillow

The product rotates within the bass drum of my Gretsch Renown.
After a few minutes of playing the kicker has moved sideways in my drum.
It doesn't change the heard sound, but changes the recorded sound as the mic position changes.
I sent Sonitus an email on 4th of July, they answered the same day asking me to measure my drum and the kicker, i did so and sent them all the requested information, since then not heard a word from them, three emails and multiple phone calls where not answered (today is the 24th of august) , i am stuck with a product that doesn't work and the manufacturer doesn't answer emails.
