EMF Meter Nuclear Radiation Detector Geiger Counter, TDS Water Tester,and Nitrate Tester. Colbo SafeCheck 4-in-1, Food and Water Quality Measuring, Radiation Meter, and Nuclear Survival Gear

I am impressed with the performance of this device. It's compact and easy to use, with clear instructions, and easy-to-read displays for each function.I have found the EMF and radiation detectors to be extremely accurate, giving me peace of mind about the safety of my home and work environment. The TDS water tester has also been very useful for ensuring that the water I am drinking at home is safe, and helps me know when it's time to replace filters. And the nitrate tester has given me peace of mind after grocery shopping.Overall, I am extremely satisfied with my purchase and would highly recommend this product to anyone. The price is also very reasonable considering the number of functions included in the device.

Do not under any circumstances purchased this unit. It is extremely poorly put together with question more material that feels like a five year olds toy. You cannot charge the item up properly because it will not stay charged longer than one minutes. With that being said, I highly suggest that you avoid this unit at all cost.

Bought it initially for TDS measurements of water. Important to me as a beer brewer and coffee lover. Started to use it for other things too very quick. Very interesting radiation meter, but where I live in the boonies it just showed me that I am very safe. EMF was a different thing, found out that my apple tv a little gizmo gives half of a microwave emf - keeping my daughter away from it.Starting using nitro meter more and more now. So far haven't found any danger, but found a lot of BS about organic, many time buying the same veggies or apples in non organic variety give you same low levels. So you can save a lot of money using it.I am definitely taking it for travel, so interesting to see how islands compare.Had some questions about keyboard, company was very responsive, big difference from Chinese manufacturers. American company does make a difference.BTW, the detector is plasticy, but very well made and pleasant to hold in your hand. I dropped it first time I put it on charge, it had no scratches, very durable.

I recently purchased the Colbo SafeCheck and have been extremely happy with my purchase. A reliable and affordable way to ensure that you and your loved ones are protected.Easy to use, with clear instructions and an easy-to-read display. It accurately detects EMF radiation from electronic devices and appliances, allowing me to make informed decisions about where to place these items in my home.I also appreciate the compact size, which makes it easy to take with me wherever I go.Overall, I highly recommend the Colbo SafeCheck to anyone concerned about the safety of their environment.

I am very pleased with the product! As soon as I received it, I plugged it in to charge. I checked everything possible – cucumbers, lemons, apples from a well-known organic store – the results are satisfying, so I'll continue buying there based on the device's readings. I also tested electronic devices for radiation. The conclusion: old laptops are critically dangerous. I am very satisfied with this product. Now, I go to the store exclusively with it! I check water, air, and products. Important for everyone who cares about their health! The advantages include its compact size, fitting into a pocket, being lightweight, and easy to use.

I'm happy with my EMF tester, it's easy to use and the device is compact. Multifunctional. I tested all the functions, they all work. The battery holds a charge for about 6 days. Clear instruction. Recommend device!

Bought this to replace my old GMC.4 functions for the price sounded too good to be true.Overall it seemed solid. However I left the device over my desk for 7 days without charging and now that I tried to charge again... it just will not boot up.It is totally bricked, no falling of the desk, no water, no accidents... it just went on without a charge for 7 days.Basically the device lasted 27 days if I count the 7 days I did not use it... utter fail.

I recently purchased the Colbo SafeCheck and I couldn't be happier with my purchase. This 4-in-1 digital device is truly a lifesaver! It not only detects EMF radiation, but also tests the TDS levels in water, nitrates, and radiation level. I love how compact and easy to use it is, making it a great addition to my family's daily routine.The clear and concise readings on the display give me peace of mind knowing that the air and water in my home are safe and suitable for us to breathe and consume. I highly recommend the Colbo SafeCheck to anyone looking for a comprehensive safety device for their home.
