I have the Oasis in-case model, it works superbly well. I monitored the humidity with a in-case hydrometer for several weeks, the Oasis keeps the humidity at about 10% higher than the actual room level (if the room is at 39% humidity, the humidity inside the guitar case stays steady at 49%). Of course, the humidity levels will depend on how dry your local climate is. The humidifier has crystals that swell up with water and maintain the moisture much longer that the average guitar humidifier. After the initial fill it took a good two weeks before adding more distilled water. What's cool is that once the humidifier begins to dry it shrivels up, so it's obvious when more water is needed. The in-case model has a magnetic strip and metal clip that fits nicely on the side of the case, no problems at all with leakage, this system is very well designed and extremely highly quality. I highly recommend it for fine jazz archtop and classical guitars. Dear Oasis, thank you for your innovative design.

Very easy to use and surprisingly effective. Needs to be checked and refilled every 2-3 days, but keeps the humidity level in my case at a very steady 47%. Great product, awesome value.

I have three of these, one for each of my instruments. I love them because they fit easily into the case and it's so easy to see when it's time to add more water (they shrivel up as the water evaporates). I also have one for my mandolin, which is a harder instrument to find humidifiers for because it is so small and, unlike guitars, has no large round sound hole. The tube has a magnet inside to attach to a little metal clamp (included) that's supposed to slide onto the edge of the guitar case. I don't use it though because my cases, which are standard "hard-shell" cases, are too thick for the little clamp. I just leave them either in the "head" section of the case or in that little extra space where the neck attaches to the guitar body. I find I'm filling it about once a week, but I live in a desert where it's REALLY dry.

Cautions: You do have to make sure to keep water in it. I let one get too dry once and it shriveled up and became stuck together and stiff. I thought for sure it was ruined. But after soaking it in warm water overnight, it became pliable enough for me to add water again (although it never became as pliable as it was when new). You also have to be careful not to overfill it or the little crystals can float out of the top accidentally. But I've not found this to be a significant problem. The only other thing that happens sometimes (which is actually more amusing than anything) is that sometimes I'll take my instrument out of the case and notice the humidifier is missing. I then proceed to search for it before noticing the magnetized little bugger is clinging to the metal tuner plates on the back of the head!

Over-all, these are my favorite humidifiers and I highly recommend them!

This humidifier seems to be doing the trick. It's simple to use, haven't had any leaking problems, and is easy to tell when it needs to be refilled. The case it is used in basically stays in the house with limited movement or bouncing around. I would be cautious of it if I was using it in a traveling case just to be sure the cylinder with the water in it doesn't rattle around the case.

I am very particular about guitar maintenance. I wipe down my guitars after every use and clean and polish periodically. I want my beautiful archtop guitar, my flat top and my hollow body around for a long time and the Oasis Humidifier will assure it maintains proper humidity level. This little gadget is so easy to use and it just fit right in the case. I've purchased additional ones to go in the cases of my other guitars. A fine product and a small price to pay for assuring your guitars area maintained properly.

This is the first dry season I am getting through with my two acoustic guitars.
I live in midwest, where the humidity is around at 40~44%, during early fall. I used
sponge type humidifiers, such as Kyser Soundhole one or Planet Wave one(the one insert
between strings), and both of them were effective, because they raised the humidity by around 5%.

However, as it got colder, with the heater running more frequently, the humidity fell below 40%, and
sponge ones were not good enough. I did some research and bought Oasis OH-6 humidifiers and am
very satisfied with result. They could raise the humidity by around 10%.
Plus, you don't need to worry about moistening sponge frequently and dripping water over your instruments.
You'll know when to refill the water as the humidifier shrinks over time(for me, this happnes about once a week).

Most people don't know that in colder northern climates, new acoustic guitars can get wrecked by the low humidity especially during the winter. Most guitars are built at about 45% humidity and need to stay at that saturation level. When they dry out the top caves in and the action becomes unplayable. This great little device can just sit in the guitar case. The water slowly absorbs and keeps the guitar at the proper moisture level. the clip fits over the side of the case and the vial has a magnet that keeps it in place. Will not be sufficient for a severely dehydrated guitar (you need one of the sponge unites that go into the body of the guitar); however, for basic hydration, this works great. Recommended!

I've a vintage classical guitar that needed a case humidfier - this one seems to do the trick and is easy to use and neat.

It is much more convenient and safer to use than the old style rat tail you tuck down in the sound hole. Plus it lasts longer.

Too bad these weren't available in 1965 when I first got my guitar!!

After getting a crack in one my acoustics last winter, I have become very particular about humidifying my guitars in their cases. I have tried the Dampit humidifier, as well as the Arion In-Case, and this Oasis is clearly the best of the bunch. It does exactly what it is supposed to do - keep the guitar at proper humidity. Except when the humidity in my apartment is very, very, very low, the Oasis keeps the case between 45% and 55% humidity all the time, just as it should. (When the room humidity is very low (e.g. below 10%), the Oasis will still keep the case 25-30% more humid than that - for my more valuable guitars, I sometimes put two Oasis humidifiers in the case when it gets very humid.)

The Oasis is small and convenient, and the metal clip makes it very easy to keep it safely and stably in your case. I find I need to refill them with water about once a week, which only takes a minute or two. The Oasis construction seems pretty solid, and I am never worried about a leak.

The Arion In-Case humidifier is decent, but it is very big and inconvenient and did not keep the humidity as high or as stable as the Oasis. And there is no good way to keep it stable and immobile when carrying the case. The Dampit was my least favorite - I found it a little more difficult to fill with water and, even though I was very careful to remove excess water before putting it in the case, it looks like it leaked a little inside my guitar! (For this reason, I will never again use a humidifier that sits directly in the guitar - water and acoustics is a bad mix.)

Ultimately, you can't go wrong with the ease, convenience and effectiveness of the Oasis. I use them in all of my guitars now. I also recommend the Caliber III hygrometer, a cheap and effective way to monitor the humidity in the case (it even has a magnet so you can stick on the same metal clip as the Oasis humidifier).

I haven't had a problem yet with it after about 2 weeks and it keeps the humidity where i need it!
