First, I'll say that these completely fixed my cabinet - I finally lost enough corners to be unplayable, and no amount of cleaning or reseating would fix them. Swapping these in, 100% of my corners are working, and the buttons feel firm and snappy.
But more than that, Tim went above and beyond for service. I was lamenting in an unrelated discord how the parts wouldn't arrive in time for my party, and how I'd have to keep jubeat offline. Tim apparently read my message, because he DM's me to tell me he's upgrading my shipping to overnight, at no cost to me. Sure enough, they're overnighted, and my machine is working. Cannot thank him enough.
I can't overstate how great of a decision it was to swap these into my cab. They make a noticeable difference in play of all levels. Take the opportunity to perform this upgrade and give your control surface a cleaning while you're at it. You won't be sorry.
Simply put, these are an excellent step up from the standard rubbers that ship with the FB9. I don't have experience with official/arcade rubbers to compare to, but these ones break in very well after only a few sessions and I haven't had a single faulty sensor after four months of near-daily play. Plus, considering the fact that buying from most sites with overseas shipping and middleman fees will often run you over a dollar a rubber, these are pretty much a steal even if they weren't so reliably good. Thanks yubiparts :)
I recently imported a Jubeat cabinet, and found that the rubbers that came with it were squishy and less than ideal, which isn't unexpected with a freshly imported machine. I ordered a set of these to replace the rubbers.
I spent about an hour and a half disassembling and cleaning the entire play field. Removed the PCBs and cleaned them with alcohol, pulled the panels, cleaned everything, installed the new rubbers, reassembled everything and tested.
Before swapping the rubbers, about 1/3 of the sensors needed rather firm pressure directly on the corner, now all of the sensors can be triggered with a light press in the center of panel.
If you feel like your cab (or controller!) needs an overhaul, these rubbers are the way to go. Highly recommended, 10/10. For the price, you cannot beat these.
great product, quick shipping. these have held up to constant arcade use very well.
