Review on 🌿 Integra Boost Medium Humidity Pack 62% (Set of 12) by Cody Mckechnie

I bought these to replace 12 packs of Broveda 62% I bought many months ago. I decided to try them as they were a bit cheaper. Well I got them and immediately took one to calibrate a couple of hygrometers, I have to see how wrong they are. So I sealed the Boost bag and 2 hygrometers in a ziplock sandwich and put them in my kitchen cupboard. Checked them after 3-4 hours, not 62%, came back after 8-9 hours, not yet. Hmm, left them there for a few days and came back to them sitting at 55%. I'll open up others and see if they do the same, but that's a bad sign. So they kind of missed their job for me so this will probably be the last time I buy them. I really wanted them to work and judging by the other reviewers they should have worked fine, maybe a bad batch.
