Seems to work well
July 1, 2020
I have used these for two years in climate ranging from cold dry winter to hot humid summer. Although our home is air conditioned, I still keep them in my guitar case full time. I have not actually tested the relative humidity, but the guitar (Taylor) keeps in excellent tune. In the coldest months when it is dry in the house, they need replacing after about 3-4 months. The warm humid season they last quite a bit longer.Well made product, and does its job. A bit of a hassle to keep handling every time I get the guitar out or put it away. The two-pack saddle needs to be put over the strings into the sound hole. Not a big deal really.

I started using these a couple of years ago and they work great. No worrying about recharging some sponge, just insert them into the holders and forget them and everything stays right at 50% humidity. If you get these be sure and pick up a small hygrometer to put in your case to keep track of when you need to change these out (especially during the dry winter months) I would suggest leaving them in the case when you are playing the guitar and keep the case closed at all times with the humidipaks inside to keep the humidity in the case. I have also been able to recharge them when they are dried out by putting them into a zip lock bag with a damp sponge. It take a couple of weeks but you can then use them again...

Works well. Will not make a better guitar but will make it sounds at its best.
