This is one of those items that makes you feel you made an investments stead of a expense.
I got it and first of all I was really surprised by the build quality, It looks totaly gorgeous and you can tell from the first look this is not a cheap item.
Use just 3 AA batteries and I've been using it for about a month and they still charged.
none at all, maybe I miss the mix of smells I had in my friedge (lol).
I was really surprised cause I placed in my friedge the same night I had it delivered.
Next day morning I woke up to go to work and when to kitchen to drink water and as soon as I opened the friedge I've noticed something was missing, after a few seconds I've realized my friedge didn't have any odor, any smell at all, I even had to stik my nose to a pineapple to smell something, for real It's been a long time ago I wasn't surprise for an item usefulness as for this one here.
Go ahead and buy it you won't regret.
