When investing in household essentials like a water purifier, one expects reliability and support, particularly from a brand as renowned as Xiaomi. Yet, my encounter with their alarming end-of-life policy unveils a potential pitfall for any Xiaomi product owner: the abrupt declaration of a product as end-of-life, rendering your investment unsupported and, in essence, valueless, irrespective of its actual state or lifespan.Three years ago (23-10-2020), I opted for a Xiaomi Smart Water Purifier, placing my family's health in the hands of what I assumed was top-tier technology supported by reliable customer service. Fast forward to today (13-02-2024), and the device has malfunctioned. I expected a straightforward, albeit paid, resolution, considering its out-of-warranty status. However, Xiaomi's response revealed the stark reality of their end-of-life policy.Despite my readiness to cover repair and part costs, Xiaomi refused service, citing the device's end-of-life status due to a single unavailable component. Paradoxically, Xiaomi continues to sell filters for this model as of today (13-02-2024), suggesting the product isn't entirely obsolete for them. This selective support highlights serious concerns regarding the durability and value of Xiaomi's offerings.This ordeal has led me to question the sustainability and ethicality of Xiaomi's post-sale support. Declaring a vital device like a water purifier as end-of-life within just three years, and denying paid repairs, is not only disheartening but also poses environmental and economic irresponsibility. It significantly erodes customer trust and loyalty, overshadowing the brand's dedication to its consumer base.I caution potential buyers to meticulously consider this policy and its ramifications. Your indispensable appliance could be merely one component short of becoming an unsupported, inoperative gadget, with Xiaomi's policies offering no solution but premature replacement. Think carefully before investing in a brand that might not uphold its products when most needed.
