I live near by a Nuclear power plant so I am always concerned about my families safety when it comes to possible radiation poisoning. Not to mention I have had to deal with Radon in the air and in my water.
 I received this Radex geiger counter to keep and eye on things here and was somewhat concerned by some of the other reviewers when they mentioned the battery life was really really bad. I have noticed that this is a new version though and I can say that battery life is not an issue anymore. I have been using mine for over two weeks and battery indicator shows still full.
 Now for the user interface that is another story. It might be just me but I had a hard time getting used to figuring how to use the menu buttons to see and adjust the settings. I was always pressing the wrong button and forced me to start all over again. Like I said it might just be me.
The back light is a very nice feature but only stays on for maybe a second and no where long enough to see what you are doing. It is just long enough to see a reading and that is it. So my suggestion would be to setup the device in good lighting so you will not be frustrated with the light going off way too early.
 I do really like how often the device updates so that you can get real time readings of your area and such. My Radon device updates only about every 5 hours but yes that is a different type of radiation being measured so can't really compare I guess.
I do believe that this new model is an improvement over the past ones. The price is not bad and does have good product support. Not a no namer that may or may not prove to be good. Hope this helps and thanks.
