I really like this air freshener works really good and smells great.Debería traer bateria,solo funciona al sol fuerteI checked the reviews before buying this and it is exactly what the reviews tell you. But the one I have, the propeller doesn't always automatically start spinning under direct sunlight but if you lightly give it a head start by spinning it with your fingers it will begin to spin on its own. The scent isn't the best but it's pretty nice. It stays stuck to my dash no problem. And some people may think since it's solar powered it will be on 24/7 but that isn't the case. It only spins when it's under sunlight.It's all good, but I don't know how the fragrance lasts?I like that it’s solar poweredGot this for my car. The scent is good but the product could use more thorough user information. The propeller spins but only in direct sunlight. The 1st one I recevied was missing parts and refubuished for some reason, DOA. The second was new but took some time to get it working. It sticks to the dash fairly good to that it doesn't move during driving and not overly to the point you can't remove it.Once I open the package for the scented disk it smelled amazing and strong but after installed and left in the car for the next day it didn't smell anymore. Only time the scent would be actually smelled is when the car is very hot and the sun and shining right on top of it. Besides the scent not being strong or long lasting the base is very strong,heavy and well made. I'll just buy some scented oils for a stronger scentPurchased this from them as a gift for my cousin's birthday. The product arrived quite quickly. I would highly recommend this product to my friends and family!Fonctionne bien
