Today is my birthday, and coincidentally the incense heater I bought arrived! I LOVE this thing! I took a small agarwood chip and cut it into approximately 1 mm by 3 mm pieces, and put about 10 of them in the foil cup on the heating plate. I set it to highest setting and 5 minutes later my room smells like heaven! Its been going now for about 20 minutes and the scent just keeps on coming! I am so happy I decided to spring for this, it beats charcoal by miles! No smoke, just a beautiful aroma. I got mine from here: https://www.mermadearts.com/p/incense-accessories/electric-incense-heater-golden-lotus It is a beautiful piece and works like a charm.
