Guitar Dehumidifier Bag Set w/Natural Bamboo Charcoal (3-50 g, 2 Pack)

it works great

I have been using the Ever Bamboo products for a few of my acoustic guitars for a couple of years now. I saw that Taylor Guitars sells this product on their website, so I figured that was a good endorsement. I had potential humidity-related issues with a new guitar and I purchased a hygrometer to monitor the humidity level inside my OHSC guitar case. There was literally no difference in the 70% humidity level in the case, with or without the bags. I was using a brand new bag set and I even used a hair dryer to dry out the case before the bag placements, just to be sure I had a baseline reference. I checked back in a couple of days, then a week, and then a few weeks, inside the guitar case with the hygrometer and new bags - no difference. With previous bags, I had also always dried out my bags in the sun every two months as suggested by the manufacturer and replaced them after a year. It was convenient to get the notification reminder emails. I had been thinking that I was doing right by my guitars for using these de-humidification packs, but they don't seem to absorb moisture at all.

Just put these in the guitar cases recently so I don't know yet how they will work. Hope they don't eliminate the smell of my guitars, which I love. But wondering about reactivation by placing them in the sun for a couple days or whatever. Wouldn't they just pull more humidity out of the air? After a time I will revisit this review when I have more info.

I live at the beach in a very humid environment. These are definitely doing the job I hoped they would. Very pleased with the product.

Hasn't changed my guitar case humidity at all. Three packs installed. Steady at 56% that's what it was before I put them in the case. Been in there long enough to work. I would not recommend this

It did not change the humidity inside my guitar case at all.

Have been using but still not sure if it's doing anything.

They are useless, total waste of money
