I play guitar, banjo and mandolin and I do guitar repairs. I usually have between 18-25 string instruments in the house at any given time. These instruments love to have indoor humidity between 40-55%! The only time that happens naturally for us here in South Central Pennsylvania is during the Summer. So we are running ultrasonic humidifiers 7-8 months of the year. I have one in every room - the guitars are all over the house - and it helps me keep it moist enough, but not too much. They are small and can be placed unobtrusively on a sheld or side table. Recently, my daughter mentioned it being too dry in her apartment, so I bought her a 6 pack as part of her Birthday present - she loves them as much as I do. Batteries last about 9 months to a year and I buy them on Amazon, too!

These are great to be able to control the humidity and temperature in your grow tent or any other thing that you would want to grow very accurate the display size is easy to see and it's really accurate because the sensitivity

Love these and can still use all for what 'I need', but took one star for only receiving 5 of 6 fully functional.It shipped in a brown cardboard colored 'Paper Thin envelope', 'no bubble or protection'. I think a little wadded paper or layer of bubble around item or in envelope would've likely prevented. I see several recent with same 1 broke display.

These work great and having the humidity helps me state my case. I work in buildings that refuse to turn on the A/C for works and I can use these to hold them accountable to OSHA regulations! They can’t argue with me when I show them to their face the temperatures they are making us work in! No excuse now!

Great for spot temperature and humidity readings. All readings were consistent and accurate.

Purchased a 6 pack but one of them came defective. Other than that they are good products. They respond to changes fairly quick.

Love these little things. Perfect to have throughout the house. They fit anywhere and are accurate.

use these to help keep track of humidity in jars while curing cannabis. cheap and invaluable to the curing process, i try to have more than i need ready to go. back in the day growers didn't use these for curing but of course we've learned a lot since then, and it's good to get the process dialed in as much as possible. for me with my ADHD, these are a no-brainer.
