Xikar Crystal Humidifier, Lasts Up to 90 Days, Reusable, Crystals Expand, Provides Perfect 70% Humidity, 2 fl oz Jar

This 2 oz container is just right for my medium sized humidor (~75 cigars.) It is a small but essential portion of keeping the large investment within at a constant level of moisture. I truly notice the difference when I use these jars faithfully. Do remember to add purified or distilled water rather than just tap as a source. The larger size of jar looks tempting but would take up too much space and this one simply works.Updated nearly two yrs later: still functions and it is better than any other product similar for the purpose. Silica gel is excellent and the vent screen is perfect.

works great just what I needed

For your average sized humidor desktop box this will work great, i.e., 50-100 cigars. Mine's new but my brother has used this for a few years and it keeps his humidor right at 70% humidity during Iowa's relatively dry winters (30-50% humidity). Mine is in a 28-quart cooler (16x16x12 in) right now and it looks like its running at 65%, so on larger humidors you may need a larger jar.

No mess and easy to use. Keeps your cigars at a consistent 70%. Lasts a long time, about 3 months. When it gets down to the add line you just refill with Xikar Humidifier Solution. The only con would be that the round container takes up space.

I was using a small cup to supplement dry humidifiers when adding a new load of cigars, or simply when new. These fill the void well and supplement your basic credo well. Especially useful during winter months when fighting dry climate conditions.

This humidifier is very small and does not allow the humidifier solution to be poured inside container. The solution just sit on the top on container. Poor design......Product is way over priced......my fault I did not shop well enough before purchasing this defective tiny humidifier. Not recommended!!

This jar works perfectly in my 50 cigar humidor. Keeps the humidity around 70%(+/-1%). I have accidentally left my humidor open for a couple of hours and this little jar brought it right back to 70%. It's been about a month now and the jar still does not need to be refilled.

Works well but doesn't keep humidity at the level I like
