"I've been using these beads in my AMS filament box and they effectively reduce moisture levels. After a particularly humid week, I recharged them in the microwave, and they returned to their original dark blue color. They seem to work well overall!"

"These drying beads are great for drying green wood bowl blanks. I place them around the bowl in a sealed container, and it dries evenly in a couple of days. The color change is a helpful indicator for saturation, making them very cost-effective and reusable!"

"I found these desiccant packs to be much more affordable than similar products. After switching from another brand, I realized these work just as well, and the rechargeability is a huge plus. I often recharge them on my dashboard while traveling, and they’re great for protecting my camera and computer gear."

"I really wanted these packs to work as advertised, and they did! I use them for items in storage, and the reusability is the best feature. Just pop them in the microwave when needed, and they're ready to use again!"

"I found these silica gel packs to be a lifesaver for my homemade dry rubs. They've kept my spices fresh and moisture-free, which is critical for their texture and potency. The quality is impressive, and I love that I can reuse them by drying them out in the oven."

"After moving across the world, I used these packs in our boxes with fabrics. They were a great size and arrived moisture-free, keeping mold and mildew at bay during the shipment. I couldn't be happier with their performance!"

"I purchased these for my son after he dropped his phone in the pool. I stuffed the phone with these packs in a sealed container, and they dried the phone within 24 hours. Both the phone and headphones were restored to normal function. Highly effective!"

"I purchased these beads to maintain dry conditions for my 3D printer filament. They've been fantastic at reducing humidity levels, dropping from 41% to just 10%!"

"After trying the Wisesorb beads, I'm really impressed! The blue-to-pink color change is super helpful for indicating when it's time to recharge. Plus, they're eco-friendly and reusable!"

"These beads are perfect for keeping my filament dry. I love that they change color, making it easy to see when they need reactivation. With this large jug, I probably won't need to buy more for a year or so!"

"I've been using the silica gel beads for a couple of months, and I'm impressed with their performance. They change color from orange to dark green, which makes it easy to know when to reactivate them. Reactivating is simple; I just put them in the oven at 225°F for about an hour. The 8-pound jug is well-packaged and has an airtight seal, making it a great value for drying 3D printer filament."

"These silica gel beads are perfect for keeping my 3D printer filament dry. They reliably maintain my dry box at 16-20% RH. When the beads start turning green, I microwave them for 10 minutes on the Defrost setting, and they're good to go again. Just a heads up, they can be slippery and bounce around if spilled."

"I bought these for my 3D printer, and I love their color-changing feature. 3.6 lbs is more than enough for my desiccant holders and spool containers. They effectively lower the humidity in my AMS, and I've noticed a significant improvement in my prints since using them."

“I've found these color-indicating silica desiccant beads to be an excellent choice for keeping my 3D printing filament dry. They absorb moisture effectively, and the orange-to-green indicator is super easy to read. They arrived vacuum-sealed, which kept them fresh, but since I have a chamber vacuum sealer, I could reseal the unused portion easily. Overall, I highly recommend them for anyone needing to control humidity!”

“This product works great for my 3D printer! It keeps my filament nice and dry. I even printed custom pods to hold these beads in my AMS, and I've had zero issues since using them!”

“I use these beads to maintain a dry environment in my storage lockup where moisture is a concern. They work fantastically! The color change lets me know when they need recharging, and I can just bake them to refresh them. It’s a simple and effective solution!”

“These packets are the perfect size for my needs! I've been using them in all my ammo cans for long-term storage, and they are working great so far.”

“I originally bought these for my car due to moisture issues from a replacement windshield. They are reusable, and I was able to recharge them in the microwave. They work so well that I even put some in my bathroom to handle the humidity from showers.”

“I placed four of these 20-gram packs in my Bambu AMS box for 3D printer filament. Initially, the humidity was at 33%, but after poking holes in the packets, it dropped to 16%. I’m upgrading my rating from 3 stars to 4 stars due to their effectiveness!”

"This was my first time buying color changing desiccant. I replaced the factory desiccant in my 3D printer filament box, and overnight, the hygrometer reading dropped to 23%. Living in South TX where the humidity is always high, this worked perfectly for my needs. I also installed it in my gun safe, and it performed similarly despite the larger air volume. It was very easy to use and pour out the desired amount, and the pop top ensures the desiccant stays fresh. I absolutely love this product!"

"I plan to use this desiccant to speed up the drying process for my 3D filament in a 4 reel drying box. This way, the filament will work its best, and I won't have to worry about excess moisture. Once dried, I can store it in airtight containers for later use."

"I tried this desiccant in my car, and it effectively absorbed moisture. The package includes a good quantity of beads and two sizes of bags, both medium and small. After they absorb moisture, I can heat them in the oven to renew their functionality. It's a handy product!"

"I've had great experiences with Dry & Dry products before, especially their beads for keeping my 3D print filament dry. So, when I discovered their food-safe alternatives, I had to try them.
