Customers find the oxygen column replacement works well, with one mentioning it’s been running for two years. The product is easy to install, taking about 10 minutes, and comes with clear instructions including pictures. They appreciate that it fits perfectly and is just what they needed. The durability receives mixed feedback – while some report it lasts about a year, others say it doesn’t last long. The oxygen level performance also gets mixed reviews, with some reporting excellent levels while others experience low oxygen warnings.
