    Heated up in the microwave as directed and upon removing from the microwave after letting it cool off the bag material melted on the bottom and tore the bag, sending hundreds of silca beads through my kitchen. Used duct tape to patch the bag, I dont feel like the bag material is made very sturdy.

    After finding a bit of mold in our storage area a few months ago, I ordered a bunch of Wisedry dessicants in various sizes. Like the other Wisedry dessicants I ordered, these 500 gram dessicants work very well. The readily absorb moisture recharge fairly easily. The one thing I dislike about these is that unlike the other Wisedry dessicants I ordered, these do not have color changing beads to let you know when they need to be recharged. Instead, the instructions say that when the weight is over 650 grams, they need to recharged. Why do I need to weigh these? Why not use color changing beads like the other ones I have? These work great, but I dislike needing to weigh them to find out if theyre full.

    We purchased 4 packages after repairing a leak around the sunroof opening of our car, to assist in removing residual moisture after wet-vac options were exhausted. We have used them continuously for a few months, and put them through a few cycles of heating in the oven -- they have really helped alleviate the situation. The weak link is seam construction on the packs - at least one of the packages started to leak dessicant pellets. I was able to reinforce the weakening end seams on a sewing machine, but that should not be necessary.

    I could never get these things to work and keep any moisture out of my car in Wisconsin. I bought them because other people had said that they worked really well in different states and countries that are cold, but not here. I can’t recommend them because it just doesn’t do anything.

    I tried drying this out in the microwave, following the instructions on the bag (1000W = 2 x 6 minutes), and a hole burned in the bag, causing the silica beads to fall out. So now the product is ruined. Otherwise, it seemed to absorb moisture from my car (prior to the failed attempt to dry out the bag).

    Bought these for wife’s 21 bronco. We’ve had back windows out, and got rained on several times. Despite having washout interior, still managed to get a mildew smell. Put both of these bags in the cargo area, smell was gone the next day. Couldn’t believe they worked that good and that fast.

    I purchased this item for the fireproof safe that I purchased. The desiccators that came with the safe seemed pretty cheap and I do not want my paperwork or other items to be ruined. I would definitely recommend.

    I put each of these in a large plastic bin that I use to store 3D printer filament. Each one has a humidity meter and at the start, they read 30%. Within a couple of hours, the bins with the Wisedry bags read 10%. I really appreciated the included sheet that told how to weigh the bags to determine when they should be recharged, and it gave instructions for doing this in a microwave, oven or leaving on a radiator (should you have one of those.)
