I saw the description for the unit and was a little hesitant to buy it, but for the price I took a chance. Glad I did.
Pros: Small, discreet, light weight, very easy to use, works great. Audio and adjustable level alert. Battery life is fantastic ~ 19 days. Measured a known test source and the unit was very accurate. Shows current levels, and accumulated dose. PC software for data logging. Excellent buy for the price. I would buy another.
Cons: No back light on the display. The display may be a slightly difficult to read for older people.
Helpful hint: It has a lanyard but if you carry it in your pants pocket place the clip the front button side to help keep it from turning on.
Update:
It was about 3 months after I purchased the Radex One that I had a minor problem. The secondary clear protective cover that protects the LCD screen detached from the unit. It is held in place by a clear glue. I emailed Quarta Rad with the Amazon order info and asked for a replacement LCD cover. The Regional Manager, Dmitry replied that the Radex One had a 1 year warranty and they were shipping out a new replacement unit, and to simply ship the old unit back usps. I received the new one 2 days later. Wow talk about fast and eager to please, these guys went way above anything I expected. If you need a compact accurate Geiger / Dosimeter at a good price, this is definitely the one to get. Quarta-Rad, you ROCK!
I have had this unit for a year now. The Radex One is a perfect grab and go unit. The compact size makes it very easy to take along, and discrete to use. The fast 10 second response time for the first reading is impressive with the best reading after 30 seconds.
The sensitive internal geiger tube runs virtually the length of the unit, which places it in class with much larger hand held units.
There is a vibration and soft audio alert that can be enabled as well as an adjustable received dose level alert. The battery life
is fantastic ~ 19 days of continuous use with an energizer battery. I measured a known test source and the unit was very accurate,
within a small percent of a unit that was 4 times as expensive. The display shows current levels, and accumulated dose. PC software
for data logging. Excellent buy for the price. I would recommend it for anyone and I would buy another.

This is a very nice unit for an excellent price. I wanted to check the granite countertops in my home and generally reassure myself that we were in a safe environment. I already had a radon detector which has shown that my home is borderline. This unit will detect other types of radiation including cosmic ray exposure in flight I took it on a long haul flight and the readings corresponded with the FEMA website values. The price is brilliant. The only drawback of this unit is the small size. It can easily be mislaid and if you are like me you will want to take it everywhere. I’m adding some pictures showing the display values on a recent long haul flight. Highly recommend.
