The transition from a brand-new IQOS ILUMA to a year-old device highlights how well it ages. Performance remains consistent, with no noticeable drop in vapor quality or session reliability. The absence of a heating blade continues to prevent residue buildup, making the device feel almost unchanged internally.

Externally, wear is limited to minor scratches and surface marks, which do not affect functionality. Battery performance declines slightly, but the device remains dependable for daily routines. Most importantly, ILUMA avoids the common long-term issues seen in earlier models, such as inconsistent heating or error messages.

While it is not maintenance-free in terms of charging and consumable costs, ILUMA proves itself as a durable, well-engineered alternative. After a year of use, it still delivers on its core promise: a cleaner, more predictable heated tobacco experience for adult smokers.
