Product review (5 stars): One Large better than two smalls
I bought this for a stand-alone end table type humidor cabinet. I had previously tried a number of the hydra units that were smaller in size. they were "little brother's" to this larger unit. I daisy-chained two of the small units together to get humidification on several different shelves within the humidor. frankly they never did a good job and we're constantly needing refilling. The reservoirs were just too small. The constant refill alarm notifications were annoying. And my cigars were never as moist and hydrated as they should be even though the product performance claims indicated even one small unit was sufficient for my size humidor. so I bought this really large version. PROBLEM SOLVED. the reservoir is huge. it does take up more space in my humidor but it works perfectly. filled it up one time more than a month ago and still haven't needed to refill it. it's probably overkill for the job to be done but now my cigars are well hydrated and I no longer am pestered by constant alarms and the need to refill smaller units every few days. Because it has so much water capacity and horsepower the unit does not have to work hard to hydrate my humidor. If you can fit the large unit in your cabinet....get it.
