Review on Highly Efficient Airtight Desiccant Dehumidifier for Industrial Use by Justin Guldin

Good orange indicator silica at a good price and great customer service. The silica color changed to green as expected and was quickly dried or recharged in the microwave using a Pyrex measuring cup. Be careful what type of container is used as it has reached over 300F and is set at 70%. It appears to hold about 20% of its dry weight in moisture, so 5 ounces held 1 ounce of moisture before it needed drying. I also use organza gift bags as they are very thin and show the color well, but only for storage and not for drying.
