Rouly 5 Packs Diatom Drying Rod Stick Absorb Absorption Rod Desiccant Water Absorption Keep Dry Stick Deodorization Gift,Moisture-Proof Clothing, Repetition Use

TLDR: They're quite effective for maintaining a clean, dry environment in delicate and moisture-prone areas.Most importantly is that they're smooth, making them gentle on delicate and porous materials like TPE silicone or similar surfaces that are most vulnerable when wet. Their ability to reduce moisture not only helps preserve such materials but also limits bacterial and mold growth by creating a less hospitable environment to grow in. They self-dry, absorb moisture very quickly, and can last a while depending on the use. I starting buying from these guys a year or so ago and haven't had any issue. I see no reason to not give 5 stars.

It works better than I expected. I put these in my wife's drawer, and the humidity level decreased a lot.

Can break easy if not handle correctly, but overall works well for what it's used for.

I've never used things like this before so I have nothing to compare them to, but these work amazingly well. You have to use them properly. If you have an object that has droplets of water on it, these aren't going to make them go away just by sucking moisture out of the air, the stick needs to touch the water. But once they touch a water droplet they will actually suck it up like a vacuum (even against gravity). It's really neat. Put a little puddle of water on a desk and then put the stick on top of it and you'll see it slowly shrinking the pool.If you need the inside of something dried out, you'll have to slide one of these sticks inside and then squeeze the object repeatedly (GENTLY, THESE THINGS ARE FRAGILE!). The stick needs to physically touch the water that you want it to absorb.As for drying out things like phones or whatnot, I haven't used it for that and I can't speak to that. I assume you'd need one of these sticks inside a ziploc bag and the object you're trying to dry out, and it'll take time. But it should do the job, the water absorption capability of this material is unreal.Apparently placing it in direct sunlight will dry it back out.(A dusty film comes off these when you rub them with your fingers, like chalk. It may be safe, it may not be. I personally wouldn't put this inside a bag of dry cat food like they advertise, or anything any animal or person would eat. Use specially made containers for that.)

These really help keep things dry and fresh. I use them in the bathroom and closets. Reusable and easy to wipe clean

Works for the things you want it for like silicone.

With a 5-pack you are not going to need to order more for a while. Each rod can be reused multiple times + they absorb the moisture pretty quickly. Yes, the efficiency decreases by each use but is nothing dramatic.

I am pleasantly surprised. Bought these for a leaking window. Window would leak where the 2 pieces meet and it locks. I put a few of these up on that ledge and waited for our next rain. This absorbed the water pretty well. It is true though....they have to be touching the water to work. And since it sits on that window ledge in the sun...it dries easily too.They are delicate though. One rolled off that ledge and broke. However, that is to be expected based on the material. I just put the pieces back up on the ledge in a row and they still work great for the window issue.
