Wisesorb 100gx2pcs Rechargeable Desiccant Packs for Storage, Color Indicating Silica Gel Packets Moisture Absorbers with Visible Window, Reusable Dehumidifier Bags for Gun Safe Closet Basement Car

Used these for a winterized boat. I'll see how the look in the spring!

First feeling.. it is good for my wardrobe and electric-appliances chest.

These work as advertised and "recharge" easily

I’ve used silica gel packs extensively for keeping telescope and camera equipment dry. At 100 grams, these packets have a higher capacity than the 10-gram packs that I’ve been using and so, I’m expecting that I’ll be able to recharge them less frequently.I like that these are in fabric bags rather than the typical perforated plastic or paper. They have nice feel to them – a substantial feel, and are stitched together nicely. The viewing window allows one to see the color change of the graduals as they absorb moisture. The packs come well sealed within thick plastic heat-sealed pouches.From my experience with other silica gel packs, you cannot expect miracles of them. It’s important that the item(s) to be protected are in a sealed container, else outside humidity will encroach quickly and it will be like air-conditioning a room with a door open to the outside.I like to seal items into a Ziploc bag along with the silica gel, while squeezing out as much air as I can. In that case these can keep the contents quite dry for quite a while. These 100-gram packets should be good for a decent sized volume – although nowhere on the box is a hint given as to the optimum air volume.I use silica gel in plastic ammo boxes or large sealed bags when possible. But ammo boxes don’t have a perfect air-tight seal.If you put these in a car, I wouldn’t expect that you could forget about them and declare – “problem solved” if the car is in a damp location. I’m sure these will help but they will quickly absorb humidity that will inevitably make its way inside.Re-activating silica gel is easy to do, just follow the instructions to heat these up for a while until the color changes back to orange(ish), which drives off the captured moisture. Then you’re ready for the next cycle. I’ve done this at least tens to hundreds of times with other silica gel packets, and I expect these to behave no differently.Overall, these seem like great desiccant packs.

Got these for my Bambu X1c since the AMS has to keep filament dry to print well. Didn't think they would work at first but I got them to work well for me.Pros+ Dry. These work well. I don't have to recharge them very often and they keep my filament very dry.+ Material. These are built well for the price. And having the window to see when they need to be recharged is very helpful. No guessing.+ Size. These fit great in the front side of the AMS. In between the feed housings. I also threw a couple into dry boxes as well.Cons+ I don't have anything negative to say about them. They work great!
