Fell apart almost immediately. But for a buck or two, it's handy and the hygrometer almost works. It does NOT hold 7 cigars if the ring size is in the mid-fifties. Not even close. But it's good for a few to have in the car.
Mine is okay. I had one problem. I used distilled water and the little blue foam grew moldy. I now just use a water pillow. Other than that it's ok.
comes with a blue neoprene-like foam for humidification. it does the job easily for smokes on the go, but is tricky to keep a sustained and consistent humidity. i use one of Boveda's small size humipaks and it holds the reading consistently. i had used duct tape to hold the bottom on (where the humidifier foam is seated), as it just slips in, not threaded. can easily inadvertently open in luggage.
