Review: Product died in less than two months -- but manufacturer was willing to send replacement - Simply put, the unit I received malfunctioned. Varying between slow and fast ticks and chirps for no good reason. Thought it may have been expected. Less than two months after I received it, it has now stopped making any noises and is broken and too late to return due to desertcart policy. Extremely disappointed. I would not buy this again from this seller. I also canceled my desertcart Prime subscription as a result. UPDATE: Contacted manufacturer after my initial review above and explained what happened and they were willing to send me a replacement unit. So the manufacturer stands by their product and it has worked flawlessly ever since. Detected radiation from airport belt scanners and other known standard sources and chirped and went back to clicking idle after a period of time properly. So, I do recommend this product. Just be sure to test and check it out that it is working properly after you receive it. This is a good product to have handy when you need to detect or be alerted to radiation, especially when unexpected. This product is a tool for added peace of mind to be able to detect an invisible threat like radiation and take appropriate action immediately to reduce exposure/harm.
Review: MRI set it off - Item works…took an mri and it was clicking at a good rate for about 2-3 days. I do recommend the product for just in case our country gets lit up.

## Questions & Answers

**Q: Is it supposed to be ticking? It ticks twice every couple of seconds. Has been doing this nonstop for months**
A: To add to the other responders to your question, the quiet ticking has nothing to do with actual detection of radiation.  Should your Nukalert pick up a significant amount of penetrating gamma radiation, it will respond with louder audible chirps about the volume of a human voice talking.  This detector is designed for 'wartime' use to scout out medium to fairly high (and immediately dangerous) levels of nuclear radiation, not detect any low level background radiation.  I hope that helps!

**Q: Does this detect high nuclear activity in time to seek shelter or medical assistance? I'm wondering if this would be a good bug out alarm.**
A: It will. I recently had a nuclear stress test. I keep mine hanging at my desk. I kept hearing this rapid ticking sound, and it was a minute before I figured out it was my NukAlert. So yeah, it will let you know if something is up.

**Q: Where can I get the batteries replaced?**
A: The company will if you send it to them. They are suppose to lasr 10 years, of course if no nuclear incidents.The company states that if you put the device next to your ear and you don't hear the internal clicks (at about 30-60 seconds) which is normal. If you hear nothing that means the battery is malfunctioning or dead. The company states to send the device back and they will replace it within the warranty.

**Q: I boughtt one years ago. How can I tell if the battery needs replaced, and how would I do so?**
A: It's guaranteed to last 10 years from the time you buy it. You can't replace the battery. When it dies you buy a new one. I quests the manufacture feels that after 10 years you got your money's worth. As far as testing it. I don't know how to do that. I do know that from time to time mine makes slight ticking noises I believe from background radiation.

### ⭐⭐⭐⭐⭐ Little expensive and quiet, but a worthy purchase
*by W***S on January 18, 2020*

Like a stated in the title, it is a little pricey, but if you have the money, it's a great buy. If you don't already have food, water, and basic sanitation products set aside then use the $100 for that, but if you're well prepared and have a little extra spending cash I'd suggest this a not only a nifty key chain to show off at the local bar, but possibly a life saving tool. The ticking can get a little annoying, it's supposed to tick once or twice every 30 seconds, but if it gets cold it's starts ticking every 10 or so seconds. I've tested it by placing it in the freezer for 20 minutes, then rapidly warming it in my hand and the beeping commences. Usually this way will get you 2 chirps every few seconds for about 5 or 10 minutes, I suppose it depends on how cold it was and how fast you warm it up. It's not very loud, which I think is something that should be improved on, but for what I do it's plenty loud.
