Great. Desiccant
This desiccant works great, keeping the relative humidity in my AMS so low that my gauges read only 10%, which is the lowest the indicator will read. My models are excellent, and the filament is dry as can be.

Seems to dry and work well
They claim it is more powerful than silica gel. I haven't tested this, but it does seem to work well. I have a decent amount of luck re-drying the material too at low temperatures for an extended period of time (80 degrees C for 24-48 hours). Happy with it so far.

Pricey, but Worth It
Long lasting and works great. Spend the extra money, it is worth it!

Great desiccant. Hygrometer required. Good life Can be recharged 100s of times.
More expensive than silica beads but much better at reaching lower humidity levels and maintaining them in a well closed container. Recharge requires higher temperatures than silica beads. Product is not impregnated with humidity sensing colorant so you will have to place a hyrgrometer in the container with it. Can be recharge 100s of times if you stay within the specs for recharge.

kept humidity levels low in ams2
works great, my ams2 pro always showed a humidity level of 64% even after drying filaments in there the humidity level would drop to 24% but then on the next day the level will rise again, i do live in a area with high humidity, but after printing the desiccant boxes to hold this desiccant and placed inside the ams2, humidity levels had stayed under 30% and it's great i can just use the ams2 heating function to recharge this desiccant as well without removing it

Great product, but...
Great product, but container doesn't hold 2lb. 2lbs is about 907 grams, but the product including the can is only around 850 grams. Not a huge deal, but worth noting. I weighed it with an accurate weight. It's still a great product, and I am happy with my purchase.

Works as advertised
Quit wasting money on the color change balls. This is rechargeable indefinitely and more effective. I printed spool holders in ASA filaments and all of the spools in my dryer have this in them. Keeps my RH in the dryer at 15% in Gulf Coast humidity.

Works great and fast!
I just got my X1C couple months ago and learned about this keeping filament dry thing recently. I only print for personal use which is not often enough to justify buying a dryer in my opinion which would also take up more space in my home office, so I opted for the route of getting more desiccant that can recharge. It's been quite humid recently in LA, and with the AMS closed most of the time with bunch of desiccant packs, it's been about 35% humidity and the app shows C or D which is not ideal and it worries me since I've been seeing more stringing recently. It started raining yesterday, so I printed the desiccant boxes for the AMS and got this item with overnight shipping. I put them in the machine sometime early this afternoon, and slowly I can see my hydrometer number keeping going down once I placed everything in the AMS :) It's been not even 10 hours, and I opened the box couple times changing filaments, the Bambu studio shows it's "B" and my hydrometer shows 10%, X1C screen shows the AMS is 19%. Either way, it's way better than 30+ prior and I'm very happy about it. So far so good, easy to fill, I don't see any powder/residue when I pour into the boxes. Yes it's a little more than the silicone stuff but this works amazing and it's also rechargeable. I'm glad I gave this a try :)
