I've been a Saje customer for as long as I can remember. When I walked into the store and noticed this product, I was very excited! I have sensitivities to certain surroundings, however, having the natural scents around me really help ease my mind. I bought some oils that I was looking forward to using in my vehicle with the car scenter and also purchased a pack of refill pads. I really enjoyed the first use! The second time I used my scenter, I noticed that the scent did not last longer than an hour. My refill pad dried out and became extremely stiff in less than two hours. Very disappointing as I'm really happy with all of my other same products. I was really looking forward to this..
