    Works great
  

*by M***O on Reviewed in the United States 🇺🇸 on April 12, 2023*

Its dry in Colorado and this product works great.  However, the instruction are meant for a more humid climate, so it requires H2O refills more frequently that is reported in the packaging if you live in a dry climate. Colorado never reaches 40% humidity.  But still works great

    Hangar didn't fit the humidifier; otherwise fine
  

*by P***S on Reviewed in the United States 🇺🇸 on December 7, 2020*

I've used Oasis humidifiers with my acoustic guitar for several winters now, so I went to them again to humidify my ukulele.  The OH-18 (ukulele) is very similar to the OH-1 (guitar) in that it is a capped water vapor-permeable tube filled with absorbent crystals and comes with a hangar to place the humidifier in the instrument's sound hole.  You periodically refill the tube with distilled water which is absorbed by the crystals to form a gel (prevents leaks) and the permeable fabric sides allow water vapor to escape and humidify the instrument.  The fabric tube will begin to shrivel when it needs more water. How long that takes will depend on the relative humidity where you store your instrument and whether you have it in a hard or soft case.  I average around 27% RH in the winter, both instruments are in soft cases and I end up adding water every 3-4 days.Overall, I'm happy with the OH-18 but there are a few drawbacks that I didn't experience with the OH-1.-The hangar did not fit the tube. The opening was too small. I had to carefully enlarge the opening with a razor blade.-I use this with a concert ukulele and find it difficult to place the humidifier in the sound hole. The tube is the same size as the one for guitars, but you place it parallel to the top of the uke instead of perpendicular to it.  I manage to get hung up in the top bracing almost every time I replace it. I can't even imagine getting it inside a soprano without a hassle.I have not had leaks with any Oasis Humidifier I've used.  A few tips:-Be very careful when you first open it so that you do not spill any crystals.  If you do, then order replacement crystals.  The crystals prevent leaks by turning the water into a gel, so you need the full amount.-Only use distilled water. Impurities in tap water can block the pores in the fabric.-Don't touch the fabric if you can avoid it. Hold the humidifier by the lid or the rubber top and bottom.-Be careful when refilling not to get the outside of the humidifier wet. Use the included syringe and go slowly-the gel will expand as it absorbs water. Do not overfill.  If you overfill, you will weaken or burst the seam on the tube and may get leaks.  I also leave my humidifier out on the counter for about 10 minutes after I've refilled it to be sure that all the water has turned to gel before placing it in the sound hole.-I think it's better to refill before the humidifier has started to significantly shrivel. There's less stress on the seam that way.  When it's reduced in volume about 25-30%, I refill it rather than waiting for it to start to really crumple.
