Bests & Worsts Reviews from Amazon

Beware: Does not add any scent to the air; Will not sync. I can do nothing but turn this on and off. Amazon will not accept the return- Despite this saying "Prime" and that it is returnable- This was delivered 3 days ago- it does not work but Amazon (the seller) will not let me return this. Update: I was finally notified by email, by Levoit, that I can return the product to them but needed to follow the correct steps which included sending them the original receipt. I ended up keeping it as a humidifier but there is still no scent, it won't sync, and only turns on and off and can't be adjusted in any way.
