The pad performs very well.
Although, you need to mod the plastic black parts a bit higher, since they are even flat with the pads you step on.
Also, the plastic arrow panels are pretty tin, so I would suggest making sure people with stiletto heels, or any small heels at all, are not playing on them. With DDRNL events, I will request people to remove their stiletto/thin heels, and play either on different shoes, or on socks.
As for the sending, I received it within 5 days from the moment they put it on the post, pretty fast.
Currently, Dnstje and me are looking into making it wireless, and adding additional lighting to the pads.
Depending on how the sensors will hold it out, we might replace them in the future with official sensors, but that's still out of the question right now.
