However, the repeated mention of manufacturing dates from several years prior and ongoing issues with the replacement tanks raised questions regarding the Consistency of quality. Overall, while the tank offers commendable functionality and customer support, potential buyers should weigh the benefits of capacity and immediate use satisfaction against the risk of durability issues over time. **
