Review: Very good product
Review: I have been looking at Geiger counters for years, but haven't been able to justify the expense (until now). Basically, I wanted it because while I don't personally work with radioactive materials or radiation, I do work with people who do, and contamination does happen. So basically I was looking for something for everyday carry. I was also interested in confirming that granite and quartz counter tops, as well as tiles, were not radioactive. I also know a lot of people with antique china (some of which is radioactive). Okay, I mostly wanted it as a gadget, but okay, I also wanted it as a prep (eyes rolling). No seriously, if you ever actually need a Geiger counter as a prep, it might be too late to buy one. So I have a few basic preps, and now this is one of them. People often wear those little radiation dosimeter badges. I have often thought this was a bit weird, because basically they tell you that you were exposed a couple of weeks ago. Whoops - it would have been nice to have known that when the exposure was happening, so you could have stopped it. So I have been looking at a number of Geiger counters for a while, and the thing that pushed me over the edge, is that the cat was about to have I-131 treatment for hyperthyroidism (this is where the patient, in this case our cat, is injected with radioactive iodine to treat hyperthyroidism). The patient (again in this case our cat) ends up fairly radioactive for a few weeks. My biggest problem upon receiving the device is that I had no way to test it. I could find literally nothing in the house that was radioactive (thank goodness). None of the china was radioactive, none of the tiles and countertops are radioactive, and I couldn't find a single old watch or clock (i.e. with radioactive glow in the dark hands). When the cat's treatment started, this problem was solved. The cat was hot, the cat's thyroid was even hotter. The litter box was hot. The cat's vomit (sometimes invisible, except to the naked foot) was hot, and the cat unfortunately in one instance missed the litter box, so then that spot of carpet was hot. I really like the device. It has a very nice display and menu options. The battery life is great: I haven't checked, but I think it lasts more than 24 hours with the display continuously on. I like that it has a rechargeable battery that you can replace, and I like that you can recharge the battery via USB-C (i.e. while the device is running). I like that it has an alarm, so if the cat sneaks up on me, I know right away. The device is very light, so I can put it in my bag and forget that it is even there. Based on what I know, GQ is quite a reputable company in the affordable Geiger counter space. The plastic looks a bit brittle, but in practice I have (unfortunately) whacked it and dropped it a couple of times, without incident (thank goodness). There are still a few Geiger counter features that I would like (again, mostly thinking of this like a gadget): - A large and sensitive paddle tube - A mica window to detect alpha particles - A gamma spectrometer I also really like the idea of ultra compact Geiger counters (like keychain ones) for everyday carry, but in practice there is a tradeoff between size and sensitivity. One thing that would be really nice for everyday carry is bluetooth connectivity. It occurs to me that one of the most likely reasons to be exposed to radiation, is if someone you know is having some sort of medical treatment and hasn't told you. It would be super embarrassing if you were in a conference room, and your Geiger counter were to go off, because surprise, your boss's boss is having brachytherapy for prostate cancer. Awkward. So for everyday carry like this, it would be better if the device were just to inconspicuously show a notification on your phone. So I don't know if this will be my last Geiger counter, but this is the one that finally bought, after years of wanting one. All in all, I would say that the perfect Geiger counter is the one that you actually own, and that you are carrying when you are exposed. This is the one that pushed me over the edge, and so for me, right now, I would say this is the perfect Geiger counter.

Perfect for my needs. I wanted a good balance between price, accuracy and quality. After several days of reviewing many radiation detectors, this one kept coming up as a highly rated product for its price point. If like me you are mainly interested in having this as a preparedness tool and playing with from time to time, I would highly recommend this device.
