My answer to: What do the colors really mean?
5 Stars
My answer to: What do the colors really mean?
Being a retired scientist and wanting to keep my bags of corn chips as crispy as possible, I had to find out how effective these packets are at different weights and colors. Of course, the benefit of this product having color-changing pellets is that you don't need to weigh them and instead can use the pellet color as your indicator for how much moisture absorption mojo they have left. For those of you who prefer not to look at graphs, my take-home message was this: If the little pellets have orange or red left in them, then I keep using them because they have greater than 33% of their absorption strength remaining. Once they are mostly green or darker, then it's time to swap them out. Now, feel free to tap that 'helpful' button and peace out. For those of you who do like to look at graphs, check out the image provided. It shows the color variation by how much moisture it absorbed. I left a brand-new packet out for 48 hours at room temperature and 65% humidity. I intermittently recorded the time, weight and color. From those data points, I was able to derive this graph. As you might expect, the absorbency rate decreases as the packet becomes gradually more saturated. This experiment used a 10g packet; the weights and absorption rates would scale proportionally. But color as an indication of absorption strength should remain consistent across products sizes. Enjoy geeking out and please hit me a 'helpful'. It encourages me to do more reviews like this. Thanks!

5.0 out of 5 stars Perfect for guitar cases
Reviewed in Canada on July 9, 2023
These things are fantastic. The small size fits easily in guitar cases. It's very humid in the summer and I typically have 3 of these in each guitar case. I check them weekly and usually recharge at the same time.

Recharging really is as simple as putting them in the microwave. I put 3 in at a time, 2 minutes per side (1200w microwave). They're very hot afterwards, so I let them cool for about 10 minutes before I use them (or return to the resealable packaging).

They seem to last a long time. I'm on my 3rd summer for some of these.
