My old one is stored under the sink now. If I don't like the oxygenics I will put the old one back and then sell the oxygenics with the coach when the time comes and keep the one that came with the coach. To tell the truth I was very happy with the OEM model and don't really know why I bought the oxygenics. It had a wide pattern on it which allowed for fast wet down and a fast rinse off.
