What response system does the punchline come stock with.

It looks like flow able silicon, but I tried flow able silicon in my Dv888 and i didn’t really like it. So where do you buy it?

They are silicone O-pads

Do you know where to buy them? I did a search but couldn’t find any.

These are the ones that come stock

But any of these pads that can fir an 888 will work
