Review on 🌼 Air Wick Scented Oil Plug-in Starter Kit - Lavender and Chamomile, 1ct by Michelle Kelley

Two of the four devices hardly smell. The two units operate noticeably on low settings, while each of the two faulty units heats up but emits little to no odor when set to high. I swapped out all the fillers for a different flavor and waited a while to rest and "restart" my heater for my nose and problem marks, no matter which room in the house it was plugged in and powered are. What I haven't done yet is measure and compare the heating temperature of each block with an infrared thermometer or thermocouple, but it's clear that two of the four blocks emit little to no odor. - Much luck!
