My old cleaner was gone, the sponge had internally detached from the stalk. The previous model (identical) has held 6 or 7 years, despite weekly use of two glass-Iso-cans. Therefore, I have resurrected a cleaner brand of Coronet and am extremely satisfied. The sponge has fine pores and durable. He is, however, at some point, wiped out from the inside of the feathered arranged stem extensions that hold the sponge through the back and forth in a pot. As described, however, this process takes a long time. But the old stalk is still a prima Rückenkratzer ;-). , ,
