wisedry 2 x 500 Gram [2.2 lbs] Rechargeable Silica Gel Car Dehumidifier, Microwave Fast Reactivated Desiccant Packets Large for Safes Closet Basement Garage Storage Moisture Absorber Bag Reusable

My truck has had a leak so among other things I got these to help reduce the humidity in the cab. I have both of them in the cab sitting on the seat when Im not in it. It only took a couple of days to go from the ~500g to >650g so Ive recharged them both in the microwave now. There was a lot of moisture in the microwave after, and they were back down to just over 500g. Im not sure how long they are going to last as the bag doesnt seem very robust. I cant say that there was a noticeable difference in the truck, but maybe it will help as I get things dried out. My seat still feels like it has collected moisture from humidity that I am hopeful these will continue to help with.

I cannot evaluate this product for its efficiency. It and one other,were placed in an sealed container (tote) and is in storage in a climate controlled facility. The box contained machined engine parts. It will remain in storage for at least 6-9 months, so I hope that the contents will be pristine when I remove them from the totes. 2 bags per tote were used, and the totes were locked by the manufacturers locking devices on each end. I will review better when I have a look at the stored components. However, I must say, that the packets were well packaged by the manufacturer and were easy to use. Thanks.

I live in Florida where tools go to die a rusty death. I recently bought another product, Simichrone Polish, along with the dessicant in an effort to keep my expensive jewelry tools in as good shape as possible. I am more than pleased with both of these purchases. The dessicant came as two large pouches. The instructions for when to re-charge (dry in the oven or microwave) are written right on the bags, which makes is really easy to figure out when they need to be dried out to keep them working. I plan to buy more. I placed one of them under the large plastic covering I keep over my rolling mill and the other I put into a large drawer where I placed as many of my tools as would fit so they will all stay protected from the high humidity we experience here in Florida. Great purchase, I will likely buy at least one more set of these bags.

The Wisedry works great in my 3D printing filament drybox. When I attempted to recharge it in my microwave oven, I followed the instructions (I thought), and ran the oven at 100% for 6 minutes, turned the Wisedry over, and ran another 6 minutes. What I didnt understand is these instructions are to be used when you have confirmed there is at least 500g of moisture (you need to weigh it). The result was the product stuck to the turntable in my microwave, and started smoldering. The seller was quick to answer my messages, and seemed very concerned about understanding what went wrong. After explaining the necessity of weighing the product before microwaving, they kindly refunded the cost of one Wisedry. I like the product, and will be buying more, but Ill weigh it before recharging. It might also be best when microwaving to check every couple minutes, and stop if it seems way too hot.

Once the packets were full of moisture, I microwaved them for 8 minutes on a microwave-safe plate as directed. I did not notice a large hole had burned through the black casing, so when I removed the plate from the microwave with the packets on it, the burning hot silica beads fell all over me and my stove and floor. They burned my arms and 1 leg where my skin was exposed. (Not blistering burns, but burns that turned red and still hurt an hour later). Thank GOODNESS no child was nearby. I now have a huge mess to cleanup once the silica cools down and my burns no longer hurt too much to go clean up in there.

I was worried about my guns rusting. These make a good option for a vault for rust prevention. You do have to dry them out occasionally.

Helps prevent car windows from fogging up.

I loaded these packs into my safe a few weeks ago and I check the contents yesterday and everything is dry. Before I bought these I had issues with high humidity levels with the documents being somewhat moist with a musty smell.

I do like that you can keep using them over and over.
