I got one of Earth Candle Companies English Pear and Freesia reed diffusers back in August last year and still have half the bottle left. Our reed diffuser still gives off the same great scent. I have it in my son's rooms to keep his room smelling fresh, if you get my meaning! These reed diffusers are definitely worth their money and I love the fact that a tree gets planted for every purchase and the fact that everything is recyclable or reusable. I have had great customer service from Hannah and delivery was really quick. I would highly recommend her company and can't wait to try another reed diffuser once my one has depleted.
