Sponge Disk for RDS-400/600

Pulled the old one out to clean it, and honestly the fit on this replacement is just as snug as the original. Makes my rice cooker feel like new again.

After nearly a year of daily use on my RDS-600, the old disk finally gave out, and this replacement snaps right into the same slot with zero wobble. Water drains exactly as fast as it did on day one, so I’m glad I stuck with the genuine part instead of a cheaper knockoff.

Felt like a brand new machine the moment I popped this in — it fits the RDS-400 perfectly, no fiddling or forcing needed. The sponge material is dense but not stiff, so it wiped down clean in seconds. I've already ordered a backup; this thing is clearly built to last.
