I've had these plugged into my kitchen and bathroom for about a month now, and the scent is still going strong on the low setting. Nice not having to swap them out every couple weeks like the old ones I used to buy.

I've had these plugged in for over a month now and the scent is still going strong, which honestly surprised me since my old refills faded after two weeks. The 50-day claim on the low setting actually holds up, and the energize scent is fresh without being overpowering in my kitchen.

The dual refill pack is handy since I can swap one out and keep the other going in the hallway outlet. On low, the scent genuinely holds for weeks instead of vanishing after a few days like my old ones. Only gripe is that even the low setting can feel a bit strong in a small bedroom.
