Gruvgear NanoMat Single Pedal

I had this in and out of my basket for over a year and eventually decided to purchase it. The first time I set it up. I found that the hi-hat stayed in place but the kick still moved. Tried it again atthe next gig, but I found that the kick run was still moving and by the end of about an hour set it had moved about 5 cm which meant that it was pushed into the kick mic in front of the kick drum and so for that reason I returned it. I was desperately hoping this would work but on a venue floor that I play all the time which is a Theatre stage with a kind of rubberized flooring it unfortunately did not stay 100% still.
