Dry capsules = Easier capping

Reviewed in the United States on June 17, 2015

Size: 1 Pack 1.5oz eaStyle: 1 PackVerified Purchase

Background/Use: I like to cap my own supplements using empty gelcaps and bulk powders. To accomplish this, I use a capping machine and buy gelatin capsules 1,000 at a time. I had trouble getting the previous caps to fit into the machine so I figured they must be absorbing moisture. So when I bought my present package of empty capsules, I also purchased this dessicant box to keep them dry. The relative humidity in my house stays between 40-50% (40-pint dehumidifier in the summer and many humidifiers in the winter) so I'm not fighting some crazy conditions to begin with.

When I got the gelcaps in, I tried them in the capping machine and though some of them were a tight fit, they worked as received. After that, I transferred them to a gallon ZipLoc bag and put this dessicant box in. 5 days later, I tried them again and to my surprise, the capsules had actually LOST MOISTURE. I was just hoping to prevent them gaining any additional moisture but to lose moisture was astounding. They all fit right into the capping machine with no resistance and in fact the top half fit so loosely that a couple of them wouldn't stay in when I flipped it upside down to press onto the filled bottom half. I did not have high hopes for this so I was looking for a solution involving calcium sulphate (the ultimate dessicant) but now I doubt I will need anything stronger than this.

Bottom line: For keeping capsules dry, this works splendidly well.

Effective and Economical Solution

Reviewed in the United States on August 4, 2018

Size: 1 Pack 1.5oz eaStyle: 1 PackVerified Purchase

I ordered 2 of these for use in a 40" gun safe. They have done a great job in eliminating any moisture and the fact that they can be "recharged" by heating them in the oven for 3 hours at 300*F makes them a great value. These dessicants let you know when they need to be "recharged" by showing a clear color through the small window on them. I purchased these in October 2016 and am writing this review August 2018 and these are still going strong. Some other reviews have noted that the window is hard to see through after heating them in the oven one time, but I haven't experienced that with the ones that I have FWIW.

Looks to be well made

Reviewed in the United States on July 8, 2016

Size: 5 Pack 1.5oz eaStyle: 5 PackVerified Purchase

I ordered eight of these for ammo cans. When I received these they had small dents in the metal, which I noted. I then reordered five more and they were packaged better and came in perfect condition. The orange light was not as noticeable as in the photograph. Everyone said you did not have to put these in the oven upon receipt. Just to be sure I put them in the oven for the required three hours. They are expensive, but if they last a life time and work well then I am willing to play the extra amount. By putting them in a small air tight ammo can, I would think that they would last a long time without having to reheat them in an oven. I have not had them long enough to be able to judge this.

handy obsorbent silica gel stuff

Reviewed in the United States on April 9, 2013

Size: 1 Pack 1.5oz eaStyle: 1 PackVerified Purchase

WHAT! No cobalt chloride?! That just chaps my hide! I occasionally put cobalt sprinkles on my ice cream. What will I do now? Anyhow, this is a good product, these things do what they are supposed to, absorb moisture and it does it rather well. Fit anywhere including your pockets. Wonder if it would work as underarm deodorant? Anyhow, need something that keeps your sensitive items dry and can be reused by heating in the oven, then this is for you! Its reasonably priced and its fun to shake. Please don't overthink these things, its a simple device that does one thing, absorb moisture and help protect you electronics or other items. Ok, it does 2 things, but you know what I mean. :) Feed it!

Product arrives pretty fast and in good condition. Does what it's supposed to, and draws out moisture. I placed it into a ziploc bag along with a camera that had condensation, condensation is all gone and my camera works fine again. 5 stars.

Reviewed in the United States on December 31, 2014

Size: 1 Pack 1.5oz eaStyle: 1 PackVerified Purchase

I purchased the orange desiccant because, as you will surely read all over the internet, including in Amazon reviews, the blue stuff is toxic. I placed one of these in a hard plastic gun case with my Mini-14. The case has an adjustable valve to limit air and other things getting into it, which I have totally closed. I don't shoot all that often, so the case is rarely opened - maybe once a month. In two months' time, the desiccant is about halfway orange, indicating to me that it is absorbing some moisture. I use Break Free CLP, Ballistol, and/or Red Line assembly lube for my firearms. I'm not an expert on chemistry so I don't know if the desiccant is possibly removing moisture from the lubricants in my rifle. It does not appear so because the rifle is still well-oiled to the naked eye. I will probably buy another one of these for my gun bag where I stow my pistol. Cheap protection against rust.

**Update - 3/4/15**
The desiccant turned almost entirely clear after about 3 months, indicating to me that it has been absorbing moisture. I followed the instructions for baking that are printed on the item and the material turned bright orange again. This continues to sit in my rifle case and my firearm does not have any rust.
