No way to review-So far its good, lets hope I never have to find out.

Folks, I bought one of these a few weeks ago and really could not tell how much life was left in it (novice, sorry...). It looked expired and after reading some of the reviews here I decided I might have gotten a bum card. I got clearance to send the card back but I contacted SafeCastle and ask for more guidance on how to tell the condition of the card and I sent them a picture of my card at their request. SafeCastle, Amber in particular, were easy to work with and a ton of help. Here's what I got back in response from them:Your card looks good and still has quite some time, if you place the card in the Freezer, it helps extend the shelf life. Based on your photo, estimating 4 years shelf life if stored below 40F. The Sensor Bar of the RADTriage will develop color equivalent to about 10 mSv in about one year if stored at room temperature, or approximately 70F. The shelf life of the RADTriage expires one year from the issue date (your specific card has an issue date of 1/2017). However if stored in the freezer, it will have a shelf life of 5 years from issue date and definitely when the color of the area surrounding the dots of the FIT (can no longer see dots). Hope this helps, let me know if you have any further questions.Thanks,AmberThat's a lot of good info!! I kept the card and have just bought a second one (oh, putting this thing in the fridge, since radiation does not care whether the card is outside, inside your home, in a car, refrigerator, anything BUT a lead can, keeping this in the fridge is a great idea--will check it each time I go for a snack!

You never know when you may be exposed to radiation and need to measure or be alerted to your received cumulative dosage. I carry this in my wallet at all times and also have a NukAlert that I also have in my vehicle or take with me on travel for additional peace of mind.This fits nicely and discreetly in a wallet, there for if you should need it. The card is easy to ready and lets you know if needs to be replaced or if you have received a significant dosage of radiation and take appropriate action.No need to freak out or be worried about radiation. Understanding that radiation is all around us, just the amount matters. If you have this you have a tool that can be used when you need it to help keep you and those around you safe in the event of an unlikely emergency radiological situation so you can make smart decisions to get to a safer location.This product needs to be replaced if the card indicators show that it needs replacement, or two years have passed, whichever occurs first.I recommend this as it is a small price to pay for peace of mind and an invaluable tool if you were to need it and have it.

Nice safety device. Hope it never really has to be used

Put one on your wallet and you’ll always know if you’ve been exposed.
