Love the form factor - fits in with a ukulele very nicely. It SEEMS accurate enough - if I put it next to a larger wall device the humidity and temp are... close. Not exact, but close. But if you're using these for instruments pretty much you're probably checking in a fairly broad way if it's "dry" or "ok" so if it's within 5% or so that's fine by me.

Seems very accurate. Bought 3, one for each of my acoustic guitar cases. All 3 match when put in a room near each other. Love the clip on.

I bought this to compare D'Addarios Bluetooth hydrometer. I calibrated with Boveda 32% and found it to be only 1% off. Works great. (not so true with D'Addario as I use them in guitar cases. Move the case and the accuracy of the hydrometer changes by up to 5%.

Great little hygrometer that just works right out of the box. If you have an expensive guitar and want to know the humidity level, this is the answer. I have a good humidifier in my home, but it just doesn't provide the level needed for my guitars. So I keep them in their case with D'Addario humidipaks and this hygrometer tells me at a glance that their in the right environment. Peace of mind .... nothing beats it.

When I first moved into my new house I felt my lever harp was out of tune quite frequently. After some discussion with my teacher she mentioned temperature and humidity as being primary factors. I have always kept the house "comfortable for a human" which I've often read is "comfortable for a harp" so the humidity became the prime suspect. I now monitor the humidity levels using this hygrometer so that I can nudge into the "comfortable" humidity range using a dehumidifier or humidifier as needed. It sounds high maintenance but harp strings are prone to break - some folks don't bat an eye if they lose 10-15 in a year and that adds up. My harp has only lost one string in almost two years! I'll have to replace them for sound quality before they actually fail. This has also helped me sleep better because when it's very dry at night it's rough on your sinuses. In the winter it can take only hours for forced-air heating to plunge the humidity into the 30s. It's easy to glance at the hygrometer and see if a little humidity or temperature adjustment will make you and your instruments more comfortable!

I leave my Oasis hydrometer on top of the door in the case so it rests right beside my neck and my case is always laid flat and not upright or sidestood and this hydrometer tells me very accurately what's going on with the temp and humidity in the case which seems to be very accurate at this point. All I did was put in the battery, turn it on and let it get accustomed to the room temp and humidity and just leave it on and place it inside the case. It stays on all the time constantly monitoring conditions inside the case. I use humidipacks but I live in Alabama so when the weather gets more stable and not so much back and forth from hot to cold then I can remove the packs and this Oasis monitor as long as it's on and measuring, should tell me when the time comes around about when to add my humidipacks back for the protection of the guitar. My only complaint is that I'm not putting the velcro sticky part on the guitar or inside the case anywhere by no means so mine just lays on top of the internal door beside the neck. In the future if they could add a cordlike line or string attachment so it can be fixed to the internal accessories door inside the case so it wont move during travel and scractch the guitar or damage the hydrometer, could be a great flexible way of attachment to more desired areas inside the case. When traveling I open the case, lift the guitar, then place the Oasis inside the internal door.

It's my second OH-2, The olded is 3 Years old Untill now I thought I knew the exact temp and humidity Now after receiving the new OH-2, There's a difference of 7% humidity between the old and the new OH-2 Which one shows the correct humidity? No thanks for having 2 OH-2 which shows different data, I had to order Cigar Oasis Caliber 4R So it will judge which is more accurate... What a headache...

I have to say this inexpensive humidity meter always reads within a percent or two from another more expensive detector I use in the room. I got this for it’s size and mobility and it works great. Easy to read for sure.
