The first time I plugged in the Wallflowers Continuous Home Fragrance Starter Kit I was nervous. I have seem some great reviews, and some terrible reviews about this product. So, I patiently waited for the scent to be released and for it to fill the air. Fortunately, it did just that, and I was left with my bedroom smelling just like lavender! I was happy that this product could fill my room with a pleasant scent and I wasn't going have to deal with any warmers or candles. A couple hours later I noticed there was a bit of a weird smell in my house that accompanied this scent. I thought it might have been a fluke, but after using different scents, I realized that the product just had this weird scent underneath. It gave me a headache, so I had to unplug them and toss it out. My headache went away as soon as the scent was no longer lingering. I really wanted to like this product, I just wish it didn't have that weird odor to it!
