## Description

Product description

Review: Impressive build quality with some high tech features - 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!
Review: Two arrived totally broken - It looks cool, buyer beware. I have purchased 2 of these now, one on desertcart 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?

## Features

- HANDY - Its compact and pocket-friendly design is discreet and durable. Only slightly larger than a ballpoint pen, the Geiger-2 is a full-featured handheld dosimeter that tucks easily into a pocket, purse, or backpack so it’s always ready when you need it.
- PLAIN & SIMPLE - The two-button function is easy to learn and extremely reliable. It accurately reads radiation levels in 20 seconds. It’s easy enough for a child to use but as accurate as professional-grade equipment.
- HIGH-QUALITY - This fully digital device has various modes to track ambient radiation and long-term statistics and allows you to set customizable daily exposure limits with alarms. Detects radiation levels as low as 0.999 μSv/h. Has the same SBM20-01 Geiger Muller tube as military-grade Geiger counters.
- ADVANCED FEATURES - Full-color digital 1.1-inch LCD display provides key information at a glance. Rechargeable 400 mAh, 3.7 V, LiPo battery. Integrated solar panel to boost charge during daylight hours. Comes with a keychain, USB-C cable, and carabiner.
- DURABLE - It is built from impact-resistant polymer. Operational in temperatures as low as 51℉ (10.5℃). It’s a perfect addition for bug-out bags and disaster prep, as it’s compact, reliable, durable, and runs on long-lasting batteries that are easy to find.

### ⭐⭐⭐ works well but with an issue
*by H***Y on February 18, 2026*

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
