Geiger-2 Portable Digital Nuclear Radiation Detector Dosimeter | Compact digital dosimeter. Detects beta, gamma, and X-ray radiation. Audible alarm. USB rechargeable.

First off let me say that I did a modest amount of research on other products (geiger counters / dosimeters etc...), as well as the Mira brand ahead of time, but am not an all knowing expert when it comes to these types of products. Things I liked: - Came well protected, and in a sleek looking giftable box. I bought this one for myself because I was really interested to see how much radiation my wife, infant, and I are exposed to on the daily where we live (the things we do to protect family, haha), but could easily see myself buying another one as great a gift for a friend or family member. - I was also very impressed with the unboxing experience. Component placement, and attention to detail for the layout and design are on point. - The product has been working exactly as described in the description, and I am moderately impressed with how long of a battery life it has for the dosimeter (tldr, dosimeter with a long lasting battery life). - The picture does not do it justice just how high quality the product feels. I knew the Mira brand makes some good stuff before buying, and so I was betting on that carrying over to this also. Can confirm that it is solid, and I have little doubt it will continue to do what it was built for (I guess what im trying to say is that it is reliable portable geiger counter / radiation meter). (again tldr, high quality geiger meter that is reliable). - The computer / display portion on the product is simple, but leaps and bounds better than literally anything else I've found out there. There is the ability to customize the settings (which honestly I did not need to change, so I just left everything on default). -The radiation measurement accuracy also seems really consistent, as it should be. No major negatives on the product yet. - The packaging says its not fully waterproof (which, I was not expecting a geiger counter to be anyways)... - The product is a little pricey, but the quality and functionality far outweighs it (in a good way). I am strongly of the opinion that when it comes to safety, this is the type of thing where I would rather get the right product, instead of buying a cheaper less capable one that would probably end up failing when I need it. Overall, a solid recommend to purchase!

It looks cool, buyer beware. I have purchased 2 of these now, one on Amazon and one direct from MIRA, both of them arrived and both of them are broken. One continually reboots and will not hold the settings, second one the left button is non-existent. E-mail directly to MIRA, filled out a ton of paperwork, I am over it. These people are over 600 dollars into me for broken not working Dosimeters. Do not get caught in a radiation area with this in your pocket or your in deep trouble. Seriously questioning the MIRA gas mask I bought now, will it work when I need it to?

While it gives a good reading, the unit that I received has a malfunctioning battery and I had to buy an external battery pack for it to stay on/be portable, otherwise it would only work when plugged into a wall. I assume this isn't a wide spread issue and isn't a big deal to me, but it is something to keep in mind

Great purchase, a little expensive, But if you're looking for a device like this, it's a better value than one might think. screen had a couple of glitches but fixed by charging.

This is a real Geiger Counter, properly detecting radiation, tested with two test sources bought on Amazon. Not like the FNIRSI GC-01 that does not detect radiation coming from the same test sources.

The MIRA Safety Upgraded Geiger-2 Portable Dosimeter can provide you with some safety and peace of mind in situations where radiation exposure might be a concern. It's designed to help you detect radiation that could be caused by naturally occurring radioactive materials in rocks and earth, contamination, or anything else that can emit radiation. Does it work perfectly? I think so, but I really don't have a reliable way to benchmark it against a known radiation source or professional-grade equipment. However, I have seen variations in the readings when testing it in different locations and conditions, so it is definitely doing something and appears to be functioning as intended. The device is compact and portable, with a clear measurement surface marked on the unit. It's straightforward to use - you don't need to be a radiation expert to operate it and get readings. While I can't verify its absolute accuracy without proper calibration equipment, I will say this: I'd rather have it in a pinch than not have it! In an emergency situation, contamination concern, or any scenario where you need to check for elevated radiation levels, having this tool available could be invaluable. If you're concerned about radiation exposure from natural sources, want to check antiques or minerals, or simply want emergency preparedness equipment, this dosimeter provides a practical detection capability at a consumer-friendly price point.

Sent a defective product and will waste your time between seller and manufacturer for return! DO NOT shop from the seller or MIRA safety

I have a different brand of dosimeter and I wanted something a little bit better so I got this one. First of all, I am not impressed. When I opened the box, it appears as if this was a used item since the screen had small scratches on it. It says on the box a new item so humm. The item wold not turn on at first so I connected it to the charger for a while and it did finally turn on. The screen is small but nice and the values I get are comparable to the other one I have. So I an say it is accurate. The other thing I do like about it, is the size is very portable. Also, the instructions are nice and well layed out and easy to understand. I have given it 3 stars because, for the money, it isn't special and doesn't do anything my $35 doesn't do. In fact, my other ones has more information, a bigger screen, better graphics, and longer battery life.
