"We have been using Cryoguard M-40 Indicators for about three years now, and have yet to receive a complaint from our customers. They like the easy, “go, no-go” indication of the temperature range of their shipments. We will continue to use this product as long as we make dry ice shipments."

"The Perth Bone & Tissue Bank has been using Cryoguard indicators to monitor the shipment of bone and tissue grafts using dry ice as a refrigerant for 10 years without any issue. Regular consignments are sent to hospitals in all states within Australia and also to New Zealand and Singapore. We find this product extremely reliable."

"We have been using the Cryoguards for about two years now. We use them in our dry shippers to monitor the temps. This makes it very easy to monitor daily if our shippers are holding their charge."
